What is the main purpose of concurrency control in a DBMS?
Correct Answer: Data consistency ensure karna jab multiple transactions saath mein execute hote hain.
  • Step 1: Understand that a DBMS (Database Management System) allows multiple users to access the database at the same time.
  • Step 2: Recognize that when many users are working on the database, they might try to change the same data at the same time.
  • Step 3: Realize that if two users change the same data simultaneously, it can lead to errors or inconsistent data.
  • Step 4: Learn that concurrency control is a method used by the DBMS to manage these simultaneous transactions.
  • Step 5: Know that the main goal of concurrency control is to keep the data accurate and consistent, even when many transactions happen at once.
