What acronym represents the properties that guarantee the reliability of database transactions?

The acronym that represents the properties which guarantee the reliability of database transactions is ACID. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these four principles are crucial for ensuring that database transactions are processed reliably.

• Atomicity ensures that a transaction is treated as a single unit. This means that either all operations within the transaction are completed successfully, or none are applied at all. If any part of the transaction fails, the entire transaction is rolled back to maintain data integrity.

• Consistency guarantees that a transaction can only bring the database from one valid state to another valid state, maintaining all defined rules, relationships, and constraints throughout the process.

• Isolation ensures that concurrently executed transactions do not affect each other's execution. This means the intermediate state of a transaction is invisible to other transactions, preserving the accuracy of operations.

• Durability assures that once a transaction has been committed, it will remain so even in the event of a system failure. This means that completed transactions are permanently stored in the database until explicitly altered or deleted.

These properties collectively ensure that database transactions are performed reliably and consistently, making ACID a foundational concept in database management systems.
