FAQs on What is Database Transaction? - Transactions in Database - DB Transactions with Examples Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. What is a database transaction? |  |
Ans. A database transaction is a single unit of work performed within a database management system that is atomic, consistent, isolated, and durable (ACID). It represents a series of operations that must be executed as a whole, either fully completed or fully aborted.
| 2. What are the properties of ACID in a database transaction? | |
Ans. ACID stands for Atomicity, Consistency, Isolation, and Durability. Atomicity ensures that all operations within a transaction are completed successfully or none of them are. Consistency ensures that the database remains in a valid state before and after the transaction. Isolation ensures that the transaction is independent of other transactions. Durability ensures that once a transaction is committed, its changes persist even in the event of a system failure.
| 3. How do database transactions ensure data integrity? | |
Ans. Database transactions ensure data integrity by following the ACID properties. Atomicity ensures that all operations are completed successfully or none of them are, preventing partial updates that could lead to inconsistent data. Consistency ensures that the database remains in a valid state before and after the transaction, maintaining data integrity. Isolation ensures that transactions are independent of each other, preventing interference that could affect data integrity. Durability ensures that changes made by a transaction persist, even in the event of a system failure, maintaining data integrity.
| 4. Can you provide an example of a database transaction? | |
Ans. An example of a database transaction could be transferring funds between two bank accounts. The transaction would involve deducting the amount from one account and adding it to another account. If any of these operations fail, the entire transaction would be rolled back to maintain data integrity and ensure that the accounts remain consistent.
| 5. Why are database transactions important in a DBMS? | |
Ans. Database transactions are important in a DBMS because they ensure data integrity, consistency, and reliability. By following the ACID properties, transactions guarantee that all operations are completed successfully or none of them are, preventing data corruption and maintaining the validity of the database. Transactions also enable multiple users to interact with the database concurrently without interfering with each other, ensuring that data remains accurate and reliable.
