Transaction and Concurrency Control questions in is an important function of DBMS, and it ensures the reliability of the databases. The DBMS, or Database Management Systems, plays a significant role in Computer Science. The Transaction & Concurrency Control for Computer Science are interdependent, and it helps with simultaneous operations involved in Database study. The Transaction Control is a sequence of actions that involves multiple processes and is passed by a single application program that updates database contents. Concurrency Control is the process of handling multiple database operations without any obstruction, and data is shared between multiple users.
Within the Transaction & Concurrency Control topics for GATE CS, there are multiple sub-topics that helps with understanding and handling the databases. These are two different topics that are mutually dependent on each other.
Transaction Control is a sequence of actions that are passed by a single application program. It includes a number of processes on the database, and is represented as an atomic unit of work. It is a number of data items within the database. The four important components are atomicity, consistency, isolation, and durability of the data processes.
This is the simultaneous execution of multiple transactions, and these are all related operations. It helps in connecting or executing transactions simultaneously over a range of shared databases.
The Transaction & Concurrency Control syllabus for GATE includes understanding the concepts for both the topics. It is an important topic under Databases, and both theoretical and conversion questions are part of the GATE Exam.
The Transaction & Concurrency Control notes for GATE CS is a complicated topic and mostly based on algorithms and concepts. Understanding the methods for conversion of the events from the database helps in the quick solving of the questions.
There is no particular Transaction & Concurrency Control book for the GATE Exam, but it is mostly recommended to follow books on DBMS.

Q. Under which category does Transaction & Concurrency Control fall?
It is an important topic while preparing for the CSE GATE exam. It falls under the umbrella topic of Database Management System (DBMS).
Q. Out of the two statements given below, which of them is true?
a) Schedule following strict two-phase locking protocol is both conflict serializable and recoverable.
b) Checkpoints in schedule are inserted for recoverability.
The correct answer is (a) because it is a basic two-phase protocol. Due to this, it provides both conflict serializability and recoverability is ensured by the two-phase locking protocol.
Q. How to prepare for Transaction & Concurrency Control?
The best way to prepare for this topic is to solve as many as Transaction & Concurrency Control quiz. It helps in better practice.
Q. What is an example of a theoretical question?
When there is a non-serial interleaving between T1 and T2 for concurrent execution, it leads to A schedule that is non-conflict serializable
Q. Where to start the preparation for Transaction and Concurrency Control for GATE CS?
Start preparing by understanding the basic concepts and clarifying the foundations. This should be followed by solving Transaction & Concurrency Control online quiz for more practice.
