What is a transaction in the context of a database management system?

Correct Answer: A transaction is a sequence of operations that are treated as a single unit of work, ensuring data integrity.

Step 1: Understand that a transaction is like a task or job that needs to be completed.
Step 2: Know that a transaction involves multiple actions or operations, such as adding, updating, or deleting data.
Step 3: Realize that all these actions in a transaction must be completed successfully for the transaction to be considered successful.
Step 4: If any part of the transaction fails, all actions are canceled, and the database remains unchanged. This is called 'rollback'.
Step 5: The purpose of a transaction is to keep the data accurate and consistent, even when there are errors or issues.
