What are ACID properties?

Q 48. What are ACID properties?



Ans : A transaction is a single logical unit of work that accesses and possibly modifies the contents of a database. Transactions access data using readand- write operations. In order to maintain consistency in a database, before and after the transaction, certain properties are followed. These are called ACID properties. ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties that guarantee that database transactions are processed reliably.



A - Atomicity

C -  Consistency

I - Isolation

D - Durability
