What are the ACID properties of a database?
Date:2023-02-17
The acronym ACID stands for Atomicity, Consistency, Isolation, and Durability.
Atomicity: All transactions within the database must be “all or nothing” in nature – either all tasks are completed or none of them are.
Consistency: The data in the database must remain consistent across all transactions. Any changes made to the data must comply with all applicable constraints, divisions, or rules.
Isolation: It must be ensured that the concurrent execution of multiple transactions does not interfere with each other. The results should be the same as if the transactions had been executed serially.
Durability: Any changes made to the database must be permanent, and should survive protracted system failures or other disruptions. The data should remain consistent even in the event of a power outage or system crash.
