FAQs on ACID Properties of Transactions Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. What are the ACID properties of transactions? |  |
Ans. The ACID properties of transactions refer to four key characteristics: Atomicity, Consistency, Isolation, and Durability. Atomicity ensures that all operations within a transaction are completed successfully or none at all. Consistency maintains data integrity before and after the transaction. Isolation ensures that multiple transactions can run concurrently without affecting each other. Durability guarantees that the changes made by a transaction are permanently saved even in the event of a system failure.
| 2. Why is it important for transactions to adhere to the ACID properties? | |
Ans. Adhering to the ACID properties ensures the reliability and correctness of database transactions. By following these principles, transactions can maintain data integrity, prevent data corruption, and ensure that the database remains in a consistent state even in the face of failures. This is crucial for ensuring the overall robustness and effectiveness of database systems.
| 3. How does Atomicity contribute to the overall reliability of transactions? | |
Ans. Atomicity ensures that all operations within a transaction are treated as a single unit of work. If any part of the transaction fails, the entire transaction is rolled back to its original state, guaranteeing that the database remains consistent. This helps prevent partial updates or inconsistencies in the data, contributing to the overall reliability of transactions.
| 4. What role does Isolation play in the context of database transactions? | |
Ans. Isolation ensures that transactions are executed independently of each other, even when running concurrently. This means that the results of one transaction are not visible to other transactions until they are committed. Isolation prevents scenarios such as dirty reads, non-repeatable reads, and phantom reads, maintaining the integrity and correctness of the data.
| 5. How does Durability ensure the persistence of data in a database system? | |
Ans. Durability guarantees that once a transaction is committed, its changes are permanently saved and will not be lost even in the event of a system crash or failure. This is typically achieved by persisting the transaction's changes to non-volatile storage, such as disk, ensuring that the data remains intact and recoverable. Durability is essential for maintaining data consistency and reliability in database systems.
