Becoming a database manager requires knowing how to deal with both technology and people. The responsibilities of a database manager typically include establishing and enforcing the data standards for the business and troubleshooting any problems with the data or the system. 

Normally, a database will contain all the data used in one application, or it will support a group of applications related to one another. For example, a business could have a payroll database, an inventory database, and an HR database.

Databases are now an integral part of modern business systems, and they play a vital role in a wide range of applications, including financial systems, customer relationship management, inventory management, and more. The database is a functional combination of hardware, software, and data. 

Data is information stored electronically in the database. The hardware includes all devices used for entering and saving data in the database. The software organizes the data and makes it available to users. 

Data Quality – the level of the data’s accuracy – is directly related to how well the data is managed.  High-quality data  is required for research, analytics, and data-driven decisions, and is a necessity for data analytics to provide useful information. Decisions made using faulty data have the potential to be disastrous. 

Database Languages

Database managers must understand database languages – also called query languages – which are used to define and access a database. These languages allow the user to perform tasks, such as searching for data, defining and updating data, and controlling access to data.

A  database management system  provides the needed database languages that allow users to express database updates and queries, which are requests for data. SQL (Structured Query Language) is the common programming language for many databases. It, and many others, use sublanguages that serve different functions to execute tasks – data control languages, data definition languages, transaction control languages, and data manipulation languages. NoSQL (Not Only Structured Query Language) databases, on the other hand, can be based on a variety of different query languages, or may not even use a query language.

Database languages are programming languages designed for searching and altering the contents of a database.

The Responsibilities of a Database Manager

Being aware of the problems common to database management, and how to deal with them, is an necessity for a good database manager. 

One of the most frequent issues a database manager faces is upscaling the system as the amount data being processed and stored increases. The performance of a database, to a large extent, depends on how well the database is maintained. Scalability describes the  ability of a database  to handle decreases or increases of the workload without impacting productivity. It is the database manager’s responsibility to keep the database (and the flow of data) running at optimum. 

A second common problem is security. Security is the responsibility of all staff working for the organization. However, the database manager is often responsible for the overall security program. With proper precautions taken, data is safe from unauthorized access and data breaches. It is important to maintain security to protect the personal information of customers and staff, and the organization’s business records. 

While many potential problems await a new database manager, another responsibility deals with data integration . As a manager, you must ensure all regularly used data sources integrate seamlessly with the business’s database. Automation is an important part of the data integration process.

Listed below are some other examples of a database manager’s typical job responsibilities:

• Hiring and training new staff for the database team
• Collaborating with other department managers and management to recognize database needs for employee files, HR documentation, customer transactions, and financial data 
• Staying up to date on the evolution of database management systems and security
• Supervising (or at least scheduling) the maintenance activities with the database team
• Organizing data within a database so it is easily retrievable
• Performing backup activities routinely to ensure the safety of the organization’s important data
• Arranging access for certain staff to the database so they can complete their job responsibilities
• Implementing the security needed to prevent hackers or other unauthorized people from accessing the organization’s data

Key Steps to Becoming a Database Manager

Most modern businesses have come to understand that data has value. Small businesses often rely on reports produced by the software platforms used in daily operations. As a business grows and matures, however, it becomes necessary to centralize the data’s storage, standardize the data’s format, and keep the data safe. This process is known as Data Management and is typically performed by the database manager and their staff.

This position requires a person with both strong technical experience and good people skills. The minimum qualifications for a database manager normally include a bachelor’s degree (preferably in some form of data technology), and previous work experience is a significant plus. 

A good database manager should be experienced in data maintenance, database management, and database design. Developing these skills takes time and cannot be learned overnight.

• A bachelor’s degree in a computer-related field is a good first step. Appropriate degrees for database managers include computer science, information technology, information systems management, or database programming. These university or college programs provide a basic understanding of database management practices, information technology, computer hardware and software, and coding. 
• A few years of work in a non-management position, such as an SQL database developer, a junior database developer, or a database assistant, provides experience and looks attractive on the resume.
• Earning specific database certifications can also help in adding to skills listed on your resume. Certifications show potential employers that you want to continue to learn and educate yourself. 
• Apply for jobs that are of interest to you. Enthusiasm really does have an impact, both during interviews and when doing the actual work. There are a variety of database management positions available, such as working for nonprofits, hospitality and tourism, education, business and finance, etc.

Database Manager vs. Database Administrator

When researching a database manager’s position on the internet, several similar-sounding positions may appear:  data manager , database engineer, database administrator, etc. The database administrator might be similar to the description of the database manager. Technically, a database manager manages and updates a database, while a database administrator can also create and delete databases. The database administrator  is normally a little higher in the workplace hierarchy, and in some organizations, might be the database manager’s boss. 

Employers, however, can sometimes be a little fuzzy on job descriptions, and it is worth checking out the data administrator positions as well. The differences between the two positions are not that significant and potential employers may merge them.

The Resume and Interview

Database management requires a broad toolbox of skills. Be sure to highlight the ways you collaborated with teams to accomplish goals. List any experience with analyzing data and emphasize times you used the data to support the business’s objectives, as well as any specific programming languages you know. Additionally, describe any certifications you have verifying your database management abilities. Also, list any books read specifically for the job on your resume.

To highlight your database management skills during  the interview , be prepared to tell specific stories of how you collaborated with others in managing and analyzing data and the impact your efforts had on business goals.

Skills a Database Manager Needs

There are a variety of skills that a database manager can find helpful. Some are people skills; some are technical skills. Examples of useful skills include:

• Communication skills and leadership skills:  In general, a manager with poor communication skills also has poor leadership skills. Good communication skills require more than the ability to speak clearly. The ability to listen can help in providing a clear understanding of staff issues and minor technical problems. 
• Knowledge of Structured Query Languages:  SQL is considered the standard language for business databases. It is such a common database language, it would be unusual for an employer to hire someone without a solid comprehension of it. It is important for a database manager to understand the use of SQL in their day-to-day work activities.

Database Manager: What it is, Functionalities and Examples

• 09 September 2021
• Sergio Darias Pérez

Nowadays almost no computer or web application could function without a database management system , so it doesn't hurt to get used to the basic concepts related to this topic. The database management system underlying any database is as fundamental as the data itself, since it would not be possible to manage the data without it.  

What is a database management system:

A database management system (DBMS) or Database Management System (DBMS) is a set of programs invisible to the end user with which the information included in a database is administered and managed. Data managers or database managers are used to manage all access to the database, since their purpose is to serve as an interface between the database, the user and the applications. Among its functions are to allow business users to store information, modify data and access the organization's knowledge assets. Likewise, the database manager is also responsible for performing queries and analysis to generate reports. In addition, database management systems can be understood as a collection of interrelated data, structured and organized in the ecosystem formed by this set of programs that access them and facilitate their management.  

What DBMSs enable:

Simply put, the database manager controls any operation executed by the user against the DB. To perform this function, it is normal that specific tools are required, such as search and reporting systems, as well as various applications. Database managers also allow the following:

• That interactions with any managed databases can always be developed separately from the programs or applications that manage them.
• The manipulation of databases, ensuring their security, integrity and consistency.The definition of databases at different levels of abstraction.

Types of database management system

Regarding their typology, database management systems are classified according to the way in which the stored data are organized:

Based on data models:

● Hierarchical system: based on a tree schema to organize the data represented in tables (rows are composed of each record and columns of each attribute) related by correspondences. ● Network system: structure with complex relationships, since each record can be traced from different paths. ● Relational system: stores data in rows and columns forming tables connected by common keys. ● Multidimensional system: spreadsheet-like structure where data is stored as it is viewed. ● Object system: stores any type of graphical data, such as image, audio or text.

Based on the number of users:

Depends on the number of personnel required to work with the databases. Thus, the database management system can be used to allow only one user to access at a time or to support multiple users. One of its advantages is that it is possible to be more specific with the type of user that can visualize and make movements in the database, always depending on the privacy needed by the company.

Based on its distribution:

● Centralized data management system: the management system and databases are stored and operated from a single location. Thus, information from each area and data management tool are reflected in a single platform. ● Distributed data management system: both the database and the management system are connected by a computer network even though they are in different locations.

Functions of a database manager:

A DBMS allows data to be defined, in addition to manipulating it, applying security and integrity measures, and recovering or restoring it after some kind of failure occurs. Some of the main functions of database managers are the following: 1. They contribute to the creation of more efficient and consistent databases. 2. They determine the storage structures of the system. 3. They facilitate data searches of any type and origin for business users. 4. They help to maintain the integrity of the company's information assets. 5. Introduce changes in the information, if required. 6. Simplify consultation processes. 7. Control the movements observed in the database.

Examples of DBMS

MySQL is a DBMS that is written in C and C++ and, in addition, is provided with a Yacc-based SQL parser with its own tokenizer (lexical scanner). In addition, the database management system is distinguished by its extensive operating system support.

2. Microsoft SQL Server

Microsoft SQL Server is a database management tool whose main query language is Transact-SQL, an implementation of the ANSI/ISO standard Structured Query Language (SQL). Some of its features are the following:

● Transaction support.

● Scalability, stability and security.

● Stored procedures support.

● Includes a powerful graphical administration environment that allows the use of DDL and DML commands graphically.

● Allows working in client-server mode, where the information and data are hosted on the server and the network terminals or clients only access the information.

Allows to manage information from other data servers.

Microsoft SQL Server is one of the leading database management systems on the market , with a wide range of software applications for business intelligence and market analytics. 

Oracle is a database management system used mainly by large companies so that they can control and manage a large amount of content from a single file.

This minimizes the risk of information loss and reduces costs. Among its features we can highlight the following: transaction support, stability and multiplatform support for Windows, Linux, Mac OS X, Unix and BDS.

Oracle's main features are the following:

● Access control, by using advanced technology that monitors who accesses the data.

● It is a convenient tool to use, as it is very intuitive.

● Secure management of data protection, in addition to backups.

The query data can be displayed in tables with the format of rows and columns with the materialized view.

Oracle is one of the most widely used management systems because it is extremely efficient, since it allows, among other things, eliminating redundant information, modifying data and even processing queries.

It is also possible to share stored information, which can be consulted through different applications. Another of its benefits is that its design language (PL/SQL) allows the application of "active" designs adaptable to the needs of the company at any given time.

A database management system, a must-have for a company

In summary, a database management system provides a series of services and languages for the creation, configuration and manipulation of the database, as well as backup mechanisms.

Organizations using a database management system can also store a description of these languages in a data dictionary and also ensure their maintenance, providing controlled access to it.

At Intelequia we know that data management, optimization and monitoring is a very important asset for any organization. That is why we offer you a large pool of professionals to provide you with advice and a set of managed services to ensure the security and availability of your data and information management.

This question also helps reveal your problem-solving skills and your capacity to collaborate with teams to achieve common goals.

Example: “At my previous job, our company was experiencing rapid growth and the existing database system could no longer efficiently handle the increasing volume of data. I was tasked with implementing a new database technology to improve performance and scalability.

After conducting thorough research, I recommended transitioning from a traditional relational database management system (RDBMS) to a NoSQL solution. This decision was based on the need for better handling of unstructured data and improved horizontal scaling capabilities. I presented my findings to the senior management team, highlighting the benefits and potential challenges of this transition.

Once approved, I led a cross-functional team in planning and executing the migration process. We started by identifying critical data sets and designing an appropriate schema for the new NoSQL database. Next, we developed custom scripts to migrate the data while ensuring its integrity. Throughout the implementation, I coordinated with various departments to minimize disruptions and provide training on the new system. The successful completion of this project resulted in significant improvements in query response times and overall system performance, ultimately supporting the company’s continued growth.”

24. How do you manage relationships with vendors and other external partners related to database management?

Fostering strong relationships with vendors and external partners is essential for a Database Manager, as these connections often play a pivotal role in the smooth functioning, maintenance, and upgrades of the systems you oversee. By asking this question, interviewers want to gauge your ability to communicate effectively, negotiate, and collaborate with these key players to ensure the best possible outcomes for your organization’s database operations.

Example: “As a database manager, maintaining strong relationships with vendors and external partners is essential for ensuring smooth operations. I start by establishing clear communication channels and setting expectations from the beginning of our partnership. This involves discussing project goals, timelines, and any specific requirements related to database management.

To maintain these relationships, I schedule regular check-ins or meetings to discuss progress, address any concerns, and share feedback. This open line of communication allows us to collaboratively resolve issues and make adjustments as needed. Additionally, I ensure that all agreements and contracts are well-documented and adhered to by both parties. This level of organization and transparency helps build trust and fosters long-lasting partnerships that contribute to the overall success of our database management initiatives.”

25. What is your experience with data privacy regulations, such as GDPR or CCPA?

Understanding data privacy regulations is essential for database managers, as they are responsible for the integrity, security, and compliance of the data they manage. By asking this question, interviewers want to gauge your knowledge of specific regulations like GDPR or CCPA and determine if you have the experience necessary to ensure their organization’s databases comply with these regulations, protecting both the company and its customers’ information.

Example: “Throughout my career as a database manager, I have gained extensive experience working with data privacy regulations such as GDPR and CCPA. In one of my previous roles at an international company, we had clients from both the European Union and California, which required us to comply with these regulations.

To ensure compliance, I collaborated closely with our legal team and other stakeholders to understand the specific requirements of each regulation. This involved implementing necessary changes in our database systems, such as creating processes for data anonymization, pseudonymization, and secure deletion. Additionally, I played a key role in developing and maintaining documentation related to data processing activities and ensuring that all employees handling sensitive data were trained on best practices for data protection.

This hands-on experience has given me a solid understanding of the importance of data privacy regulations and how they impact database management. It has also equipped me with the skills needed to adapt quickly to new or updated regulations and implement appropriate measures to maintain compliance.”

26. Have you ever had to deal with a database breach? If so, how did you handle it?

Database breaches can have serious consequences for a company, its clients, and its reputation. When asking this question, interviewers want to gauge your experience in handling such critical situations, your ability to respond quickly and effectively, and how you prioritize data security. Your response will provide insight into your problem-solving skills and your commitment to maintaining the integrity of the databases you manage.

Example: “Yes, I have experienced a database breach in my previous role as a Database Manager. When the breach was discovered, I immediately followed our company’s incident response plan to mitigate any further damage and secure the affected systems. The first step involved isolating the compromised server from the network to prevent unauthorized access and potential spread of the issue.

Once the server was isolated, I collaborated with our IT security team to conduct a thorough investigation to identify the root cause of the breach and assess the extent of the damage. We determined that an unpatched vulnerability had been exploited by the attacker. After identifying the vulnerability, we applied the necessary patches to all relevant systems and implemented additional security measures to prevent future breaches.

After resolving the technical issues, I worked closely with senior management and legal counsel to ensure proper communication with affected stakeholders, including employees and clients. We also reviewed and updated our security policies and procedures to strengthen our overall cybersecurity posture. This experience reinforced the importance of proactive security measures and regular system updates to protect sensitive data effectively.”

27. Explain the concept of database replication and its benefits.

Your potential employer wants to be sure you understand the importance of maintaining the integrity and accessibility of their data. Database replication is a method for ensuring that multiple copies of data are kept up-to-date across different locations or systems, which can improve performance, increase data availability, and provide redundancy in case of system failures. Demonstrating your knowledge of this concept shows that you are well-versed in critical strategies for maintaining a reliable and efficient database system.

Example: “Database replication is the process of creating and maintaining multiple copies of a database across different locations or servers. This technique ensures that all replicas remain synchronized, providing consistent data access to users regardless of their location.

The benefits of database replication are numerous. First, it enhances data availability by allowing users to access data from the nearest replica, reducing latency and improving performance. Second, it provides redundancy and fault tolerance, as if one server fails, other replicas can still serve user requests, minimizing downtime. Third, replication helps distribute workload among multiple servers, preventing overloading on a single server and ensuring optimal system performance. Lastly, it facilitates backup and recovery processes, as having multiple copies of the database allows for quicker restoration in case of data loss or corruption.”

28. Describe your experience with implementing high availability and disaster recovery solutions for databases.

When it comes to managing databases, ensuring data integrity and uptime are two of the most critical aspects. Databases are the backbone of many businesses, and any downtime or data loss can lead to significant financial and reputational damage. By asking this question, interviewers want to gauge your expertise in implementing high availability and disaster recovery solutions, which are essential for minimizing the impact of hardware failures, power outages, or other unexpected events on a company’s operations.

Example: “Throughout my career as a Database Manager, I have implemented high availability and disaster recovery solutions for various organizations. One notable project involved setting up an Always On Availability Group for a SQL Server database to ensure minimal downtime in case of server failure. This solution allowed us to maintain multiple replicas of the primary database on separate servers, providing automatic failover capabilities.

To further enhance our disaster recovery strategy, we also employed regular database backups and log shipping to a geographically distant data center. This ensured that even in the event of a catastrophic event affecting the primary site, we could quickly restore operations using the remote backup. These combined efforts significantly improved the organization’s overall resilience and minimized potential disruptions to critical business processes.”

29. How do you ensure that your team follows best practices in database design and management?

The aim of this question is to gauge if you have a comprehensive understanding of the importance of database management best practices, as well as your ability to effectively communicate and enforce these practices with your team. Demonstrating your knowledge of industry standards, and your ability to guide and train your team members, will show the interviewer that you are committed to maintaining a high level of performance and minimizing potential errors within the organization’s database systems.

Example: “To ensure that my team follows best practices in database design and management, I start by providing them with clear guidelines and documentation on the standards we adhere to. This includes industry-accepted principles such as normalization, indexing strategies, and data integrity constraints. Regular training sessions are also organized to keep everyone up-to-date with the latest trends and techniques.

Another key aspect is fostering a culture of collaboration and open communication within the team. Encouraging peer reviews and group discussions allows for knowledge sharing and helps identify potential issues early in the process. Additionally, implementing version control systems and change management procedures ensures that any modifications to the database structure are well-documented and traceable.

To further support adherence to best practices, I establish performance metrics and conduct regular audits to assess the quality of our databases. This enables me to identify areas for improvement and provide constructive feedback to the team, ultimately ensuring that our databases are designed and managed effectively while aligning with overall business goals.”

30. Can you provide an example of a time when you had to make a difficult decision related to database management, and how you handled it?

As a database manager, you’ll face various challenges that require critical thinking and problem-solving skills. Interviewers want to know how you approach difficult decisions, particularly those that impact the organization’s data integrity, security, and overall performance. Your ability to navigate these situations demonstrates your expertise, adaptability, and commitment to maintaining high standards in database management.

Example: “There was a situation where our company was experiencing rapid growth, and the existing database infrastructure was struggling to keep up with the increasing demands. Performance issues were becoming more frequent, affecting both internal operations and customer-facing applications. I had to decide whether to invest in upgrading the current system or migrate to a new, more scalable solution.

After conducting thorough research and consulting with my team, we determined that migrating to a cloud-based database would be the most cost-effective and efficient long-term solution. However, this decision involved risks such as potential downtime during migration and ensuring data security in the new environment.

To mitigate these risks, I developed a detailed migration plan, including extensive testing of the new platform, backup strategies, and staff training on the updated technology. We also collaborated closely with the cloud service provider to ensure a smooth transition. The result was a successful migration with minimal disruption to business operations, leading to improved performance and scalability for future growth.”

Project #4 - concurrency control.

Do not post your project on a public GitHub repository.

This project is all about adding support for transactions in BusTub! To achieve this, you will add a lock manager to your system in your database system and then use it to support concurrent query execution. The lock manager is responsible for keeping track locks on both tables and tuples in five different modes: intention-shared, intention-exclusive, shared-intention-exclusive, shared, and exclusive. The lock manager will process lock requests from transactions, grant locks to transactions, and check if locks are released appropriately based on the transaction's isolation level.

The project is comprised of the following three tasks:

This is a single-person project that will be completed individually (i.e., no groups).

• Release Date: Nov 15, 2022
• Due Date: Dec 11, 2022 @ 11:59pm

Project Specification

Like the previous projects, we are providing you with stub classes that contain the API that you need to implement. You should not modify the signatures for the pre-defined functions in these classes. If you do this, it will break the test code that we will use to grade your assignment, and you will end up getting no credit for the project. If a class already contains certain member variables, you should not remove them. But you may add private helper functions/member variables to these classes in order to correctly realize the functionality.

The correctness of this project depends on the correctness of your implementation of previous projects; we will not provide solutions or binary files aside from the B+ Tree wrapper from Project #3 .

Task #1 - Lock Manager

To ensure correct interleaving of transactions' operations, the DBMS will use a lock manager (LM) to control when transactions are allowed to access data items. The basic idea of a LM is that it maintains an internal data structure about the locks currently held by active transactions. Transactions then issue lock requests to the LM before they are allowed to access a data item. The LM will either grant the lock to the calling transaction, block that transaction, or abort it.

In your implementation, there will be a global LM for the entire system (similar to your buffer pool manager). The TableHeap and Executor classes will use your LM to acquire locks on tuple records (by record id RID ) whenever a transaction wants to access/modify a tuple.

This task requires you to implement a table-level and tuple-level LM that supports the three common isolation levels: READ_UNCOMMITED , READ_COMMITTED , and REPEATABLE_READ . The Lock Manager should grant or release locks according to a transaction's isolation level. Please refer to the lecture slides for a refresher on isolation levels.

In the repository, we are providing you with a Transaction context handle ( include/concurrency/transaction.h ) with an isolation level attribute (i.e., READ_UNCOMMITED , READ_COMMITTED , and REPEATABLE_READ ) and information about its acquired locks. The LM will need to check the isolation level of transaction and expose correct behavior on lock/unlock requests. Any failed lock operation should lead to an ABORTED transaction state (implicit abort) and throw an exception. The transaction manager ( include/concurrency/transaction_manager.h ) would further catch this exception and rollback write operations executed by the transaction.

We recommend you to read this article to refresh your C++ concurrency knowledge. More detailed documentation is available here .

REQUIREMENTS

The only file you need to modify for this task is the LockManager class ( concurrency/lock_manager.cpp and include/concurrency/lock_manager.h ). You will need to implement the following functions:

• LockTable(Transaction, LockMode, TableOID)
• UnlockTable(Transction, TableOID)
• LockRow(Transaction, LockMode, TableOID, RID)
• UnlockRow(Transaction, TableOID, RID)

The specific locking mechanism taken by the lock manager depends on the transaction isolation level, whether it is a table-level or tuple-level lock, and the type of lock involved. You should first take a look at the transaction.h and lock_manager.h to become familiar with the API and member variables we provide. Then, carefully read through [LOCK_NOTE] , [UNLOCK_NOTE] , and individual function specs in lock_manager.h to understand the expected behavior for your LM.

We also recommend to review the isolation level and hierarchical locking concepts since the implementation of these functions shall be compatible with the isolation level of the transaction that is making the lock/unlock requests. You have the freedom of adding any necessary data structures in lock_manager.h . You should consult with Chapters 15.1-15.2 in the textbook and isolation level concepts covered in lectures to make sure your implementation satisfies the requirement.

• While your Lock Manager needs to use deadlock detection, we recommend testing and verifying the correctness of your lock manager implementation first without any deadlock handling before adding detection mechanisms.
• You will need some way to keep track of which transactions are waiting on a lock. Take a look at LockRequestQueue class in lock_manager.h
• When do you need to upgrade a lock? What operations on the LockRequestQueue is needed when you need to update a table/tuple lock?
• You should maintain the state of a transaction. For example, the states of transaction may be changed from GROWING phase to SHRINKING phase due to unlock operation (Hint: Look at the methods in transaction.h )
• You should also keep track of locks acquired by a transaction using *_lock_set_ so that when the TransactionManager wants to commit/abort a transaction, the LM can release them properly.
• Setting a transaction's state to ABORTED implicitly aborts it, but it is not explicitly aborted until TransactionManager::Abort is called. You should read through this function and provided tests to understand what it does, and how your lock manager is used in the abort process.

Task #2 - Deadlock Detection

Your lock manager should run deadlock detection in the background to abort blocking transactions.

More precisely, this means that a background thread should periodically build a waits-for graph on the fly and break any cycles.

The graph API you must implement and use for your cycle detection along with testing is the following:

• AddEdge(txn_id_t t1, txn_id_t t2) : Adds an edge in your graph from t1 to t2. If the edge already exists, you don't have to do anything.
• RemoveEdge(txn_id_t t1, txn_id_t t2) : Removes edge t1 to t2 from your graph. If no such edge exists, you don't have to do anything.
• HasCycle(txn_id_t& txn_id) : Looks for a cycle by using the Depth First Search (DFS) algorithm. If it finds a cycle, HasCycle should store the transaction id of the youngest transaction in the cycle in txn_id and return true. Your function should return the first cycle it finds. If your graph has no cycles, HasCycle should return false.
• GetEdgeList() : Returns a list of tuples representing the edges in your graph. We will use this to test correctness of your graph. A pair (t1,t2) corresponds to an edge from t1 to t2.
• RunCycleDetection() : Contains skeleton code for running cycle detection in the background. You should implement your cycle detection logic in here.

How you choose to implement the graph is up to you as long as your implementation supports the above API. Those functions are what we will use to test your code.

• Your background thread should build the graph on the fly every time it wakes up. You should not be maintaining a graph, it should be built and destroyed every time the thread wakes up.
• Your DFS Cycle detection algorithm must be deterministic . In order to do achieve this, you must always choose to explore the lowest transaction id first. This means when choosing which unexplored node to run DFS from, always choose the node with the lowest transaction id. This also means when exploring neighbors, explore them in sorted order from lowest to highest.
• When you find a cycle, you should abort the youngest transaction to break the cycle by setting that transactions state to ABORTED.
• When your detection thread wakes up, it is responsible for breaking all cycles that exist. If you follow the above requirements, you will always find the cycles in a deterministic order. This also means that when you are building your graph, you should not add nodes for aborted transactions or draw edges to aborted transactions.
• Your background cycle detection algorithm may need to get a pointer to a transaction using a txn_id . We have added a static method Transaction* GetTransaction(txn_id_t txn_id) to let you do that.
• You can use std::this_thread::sleep_for to order threads to write test cases. You can also tweak CYCLE_DETECTION_INTERVAL in common/config.h in your test cases.
• Remember that a waits for graph is a directed graph.
• A waits for graph draws edges when a transaction is waiting for another transaction. Remember that if multiple transactions hold a lock on the same object, a single transaction may be waiting on multiple transactions.
• When a transaction is aborted, make sure to set the transaction's state to ABORTED . The transaction manager will take care of the explicit abort and rollback changes.
• A transaction waiting for a lock may be aborted by the background cycle detection thread. You must have a way to notify waiting transactions that they've been aborted.

Task #3 - Concurrent Query Execution

During concurrent query execution, executors are required to lock/unlock tuples appropriately to achieve the isolation level specified in the corresponding transaction. To simplify this task, you can ignore concurrent index execution and just focus on table tuples.

You will need to update the Next() methods of some executors (sequential scan, insert, and delete) implemented in Project 3. Note that transactions should abort when lock/unlock fails. Although there is no requirement of concurrent index execution, we still need to undo all previous write operations on both table tuples and indexes appropriately on transaction abort. To achieve this, you will need to maintain the write sets in transactions, which is required by the Abort() method of transaction manager. When the executor fails to acquire a lock, you should throw a ExecutionException so that the execution engine will tell the user that the query failed and should be aborted.

You should not assume that a transaction only consists of one query. Specifically, this means a tuple might be accessed by different queries more than once in a transaction. Think about how you should handle this under different isolation levels.

More specifically, you will need to add support for concurrent query execution in the following executors:

In this task, you are also required to pass Terrier Benchmark without segfault and deadlocks.

Terrier Benchmark

In a galaxy far, far away, there is a planet. On the planet live Jack Russell terriers in a highly-civilized society. There is an increasing popularity of NFTs (non-fungible token). One day the terriers decide to find some database system to track their NFTs, and BusTub is one of the candidate system.

Each terrier has a unique ID. Each NFT also has a unique ID. The terriers first create an NFT table, which records which terrier each NFT belongs to.

Then they run transaction at repeatable read isolation level to exchange NFTs. There will be multiple terriers running transactions at the same time (in multiple threads).

In the exchange process, they want to know how many NFTs each terrier owns.

You will need to ensure BusTub does not crash or deadlock while producing the correct result during the benchmark process for 30 seconds, so that the terriers do not lose track of their NFTs.

You can run the Terrier benchmark using the following command:

Leaderboard Task (Optional)

Terriers measure database performance by throughput -- counting how many transactions are processed within a given amount of time. In the leaderboard task, you will need to optimize BusTub to process NFT exchanges efficiently.

The terrier benchmark will start 2 threads to exchange NFTs and start 2 other threads to count how many NFTs each terrier owns. The final QPS (query per second) is computed as:

Here is a list of recommended optimizations:

Predicate pushdown to SeqScan: You can implement predicate filter in SeqScanExecutor so that you can lock fewer tuples when doing SeqScan. You can enable MergeFilterScan optimizer rule merge_filter_scan.cpp and implement this optimization.

Implement UpdateExecutor: You can implement UpdateExecutor so that tuples can be updated in-place and will probably be more efficient. Modify terrier_benchmark_config.h to instruct Terriers to use UPDATE for exchaging NFTs.

Use Index: You can create an index over the NFT table, and then push the predicate down to IndexScanExecutor to do index lookup. For example, if we have an index over NFT's id column, the SELECT * FROM nft WHERE id = 1 can actually be done like (1) extract id = 1 predicate and (2) directly call GetValue(1) over the index, instead of doing a full index scan or table scan. You will need to update index scan plan to facilitate this optimization. Modify terrier_benchmark_config.h to instruct Terriers to create an index before exchanging NFTs.

Note: You do not need to make your optimization perfect. For example, if you want to implement index lookup + update executor, you only need to consider the case for the terrier benchmark: the index only contains a fixed amount of items and the RID never changes.

Note: The terrier benchmark will run in debug mode without index creation and without update executor first, and then run in release mode with your specified optimizations.

Instructions

Setting up your development environment.

See the Project #0 instructions on how to create your private repository and setup your development environment.

You must pull the latest changes on our BusTub repo for test files and other supplementary files we have provided for you. Run `git pull`.

You can test the individual components of this assignment using our testing framework. We use GTest for unit test cases. You can compile and run each test individually from the command-line:

Important: These tests are only a subset of the all the tests that we will use to evaluate and grade your project. You should write additional test cases on your own to check the complete functionality of your implementation.

Development Hints

Instead of using printf statements for debugging, use the LOG_* macros for logging information like this:

To enable logging in your project, you will need to reconfigure it like this:

The different logging levels are defined in src/include/common/logger.h . After enabling logging, the logging level defaults to LOG_LEVEL_INFO . Any logging method with a level that is equal to or higher than LOG_LEVEL_INFO (e.g., LOG_INFO , LOG_WARN , LOG_ERROR ) will emit logging information.

Use assert to force check the correctness of your implementation.

Please post all of your questions about this project on Piazza. Do not email the TAs directly with questions. The instructor and TAs will not debug your code. Particularly with this project, we will not debug deadlocks.

Grading Rubric

Each project submission will be graded based on the following criteria:

• Does the submission successfully execute all of the test cases and produce the correct answer?
• Does the submission execute without any memory leaks?

Note that we will use additional test cases that are more complex and go beyond the sample test cases that we provide you.

4 Reasons Why Managers Fail

• Swagatam Basu,
• Atrijit Das,
• Vitorio Bretas,
• Jonah Shepp

Nearly half of all managers report buckling under the stress of their role and struggling to deliver.

Gartner research has found that managers today are accountable for 51% more responsibilities than they can effectively manage — and they’re starting to buckle under the pressure: 54% are suffering from work-induced stress and fatigue, and 44% are struggling to provide personalized support to their direct reports. Ultimately, one in five managers said they would prefer not being people managers given a choice. Further analysis found that 48% of managers are at risk of failure based on two criteria: 1) inconsistency in current performance and 2) lack of confidence in the manager’s ability to lead the team to future success. This article offers four predictors of manager failure and offers suggestions for organizations on how to address them.

The job of the manager has become unmanageable. Organizations are becoming flatter every year. The average manager’s number of direct reports has increased by 2.8 times over the last six years, according to Gartner research. In the past few years alone, many managers have had to make a series of pivots — from moving to remote work to overseeing hybrid teams to implementing return-to-office mandates.

Data Security in Payroll Data Validation Reports

Configure the Data Validation Report to run based on the profile of the user who submits the report.

For example, if a user has access to employees only within a specific payroll or department, you can configure the report to only report data for those employees. The access the user has is defined by the data security profile attached to the user's role.

Here are the tasks required to configure and run the report based on the profile of the user submitting the report:

Sign in as IT Security Manager and define HCM data roles and setup data security. Assign the data roles to the application user as per the requirement of your enterprise.

Sign in as Payroll Manager and secure the 'Payroll Data Validation Report' at the Legislative Data Group level.

Sign in as application user to whom the privileges are assigned and run the report.

Define Data Roles and Assign Data Roles to the Application User

No predefined HCM data roles exist. While creating an HCM data role, include a job role. The secured HCM object types that the job role accesses are identified automatically, and sections for the appropriate security profiles appear. Select or create security profiles for those object types in the HCM data role.

For each object type, you can include only one security profile in an HCM data role, which is known as Security Profile. Consider the following to complete the setup.

You must have the IT Security Manager Job role to perform this task.

To create an HCM data role, use the Assign Security Profiles to Role task in the Setup and Maintenance work area.

For more information on setting up the data security as per the requirement of the enterprise, see Oracle Human Capital Management Cloud Securing HCM.

Here are the steps required to configure the report based on the profile of the user submitting the report.

Search and select the Payroll Flow Patterns task from Payroll in My Client Groups on your Home page.

Search for the Run Payroll Data Validation Report flow pattern.

Select the required Legislative Data Group .

Click Edit .

Click Go to Task and click Edit .

Select the row and click the Edit on the tool bar for the row.

Select the Secure Process or Report check box and click Save .

Alternately, you can click on Remove all Updates .

Repeat these steps for each Legislative Data Group, where the setting must apply. This configuration, although done on the delivered flow pattern, is preserved during patching and upgrades.

Submit Report

When you submit the report, consider the following:

Select the Payroll Statutory Unit (PSU) from a secured list of values. If the user's data security is restricted by the PSU, then the user can only run the report for that PSU they have access to, even if the report is run as the elevated user by default.

If the user's data access is restricted based on other attributes like department or payroll, configure the report based on the user profile. This is only if you must restrict the report to the profile of the user submitting the report and only data for the department or payroll is reported.

Gig workers are writing essays for AI to learn from

• Companies are hiring highly educated gig workers to write training content for AI models .
• The shift toward more sophisticated trainers comes as tech giants scramble for new data sources.
• AI could run out of data to learn from by 2026, one research institute has warned. 

As artificial intelligence models run out of data to train themselves on, AI companies are increasingly turning to actual humans to write training content.

For years, companies have used gig workers to help train AI models on simple tasks like photo identification , data annotation, and labelling. But the rapidly advancing technology now requires more advanced people to train it.

Companies such as Scale AI and Surge AI are hiring part-timers with graduate degrees to write essays and creative prompts for the bots to gobble up, The New York Times reported . Scale AI, for example, posted a job last year looking for people with Master's degrees or PhDs, who are fluent in either English, Hindi, or Japanese and have professional writing experience in fields like poetry, journalism, and publishing.

Their mission? To help AI bots "become better writers," Scale AI wrote in the posting.

And an army of workers are needed to do this kind of work. Scale AI has as many as tens of thousands of contractors working on its platform at a time, per the Times.

"What really makes the A.I. useful to its users is the human layer of data, and that really needs to be done by smart humans and skilled humans and humans with a particular degree of expertise and a creative bent," Willow Primack, the vice president of data operations at Scale AI, told the New York Times. "We have been focusing on contractors, particularly within North America, as a result."

The shift toward more sophisticated gig trainers comes as tech giants scramble to find new data to train their technology on. That's because the programs learn so incredibly fast that they're already running out of available resources to learn from. The vast trove of online information — everything from scientific papers to news articles to Wikipedia pages — is drying up.

Epoch, an AI research institute, has warned that AI could run out of data by 2026.

So, companies are finding more and more creative ways to make sure their systems never stop learning. Google has considered accessing its customers' data in Google Docs , Sheets, and Slides while Meta even thought about buying publishing house Simon & Schuster to harvest its book collection, Business Insider previously reported.

Title: llm2vec: large language models are secretly powerful text encoders.

Abstract: Large decoder-only language models (LLMs) are the state-of-the-art models on most of today's NLP tasks and benchmarks. Yet, the community is only slowly adopting these models for text embedding tasks, which require rich contextualized representations. In this work, we introduce LLM2Vec, a simple unsupervised approach that can transform any decoder-only LLM into a strong text encoder. LLM2Vec consists of three simple steps: 1) enabling bidirectional attention, 2) masked next token prediction, and 3) unsupervised contrastive learning. We demonstrate the effectiveness of LLM2Vec by applying it to 3 popular LLMs ranging from 1.3B to 7B parameters and evaluate the transformed models on English word- and sequence-level tasks. We outperform encoder-only models by a large margin on word-level tasks and reach a new unsupervised state-of-the-art performance on the Massive Text Embeddings Benchmark (MTEB). Moreover, when combining LLM2Vec with supervised contrastive learning, we achieve state-of-the-art performance on MTEB among models that train only on publicly available data. Our strong empirical results and extensive analysis demonstrate that LLMs can be effectively transformed into universal text encoders in a parameter-efficient manner without the need for expensive adaptation or synthetic GPT-4 generated data.
