What is the purpose of concurrency control in a DBMS?
Correct Answer: Concurrency control ensures data integrity.
- Step 1: Understand that a DBMS (Database Management System) is used to manage data in a database.
- Step 2: Know that a transaction is a sequence of operations performed as a single logical unit of work.
- Step 3: Realize that multiple transactions can happen at the same time, which is called concurrency.
- Step 4: Understand that when transactions run at the same time, they can interfere with each other.
- Step 5: Learn that concurrency control is a method used to prevent this interference.
- Step 6: Know that the main goal of concurrency control is to maintain data integrity, ensuring that the data remains accurate and consistent.
- Step 7: Conclude that without concurrency control, the database could end up with incorrect or corrupted data.
