Questions & Step-by-Step Solutions
What does concurrency control in a DBMS ensure?
Correct Answer: Data integrity
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 accessing and changing data at once, it can lead to problems like data being overwritten or lost.
Step 3: Learn that concurrency control is a method used by the DBMS to manage how users interact with the data.
Step 4: Know that concurrency control ensures that even when multiple users are working on the database, the data remains accurate and consistent.
Step 5: Conclude that the main goal of concurrency control is to maintain data integrity, meaning the data stays correct and reliable despite simultaneous access.
Concurrency Control – Concurrency control is a mechanism in a DBMS that manages simultaneous operations without conflicting, ensuring data integrity and consistency.
