What are the acid properties of a transaction?

Question

Accepted Answer

The acid properties of a transaction refer to its key characteristics for ensuring reliability and consistency in database systems.

Atomicity: A transaction is considered atomic if it is treated as a single unit of work that either completes in its entirety or is fully rolled back.
Consistency: This property ensures that a transaction transforms the database from one consistent state to another consistent state.
Isolation: Transactions should be isolated from each other to prevent interference and ensure data integrity.
Durability: Once a transaction is committed, its changes are permanent and will not be lost even in the event of a system failure.
Example: If a bank transfer transaction involves deducting funds from one account and adding them to another, all these operations should be atomic to maintain data integrity.
