What is the main goal of concurrency control in a DBMS?
Correct Answer: Data consistency
- 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: Know 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: The main goal of concurrency control is to keep the data consistent and accurate, even when multiple transactions are happening at once.
