What Is ACID and Why Use It?

ACID stands for four traits of database transactions:

Atomicity - An operation either succeeds completely or fails; operations do not leave incomplete data in the system.

Consistency - Once an operation completes, the results of that operation are visible to every subsequent operation.

Isolation - Operations completed by one user do not cause unexpected side effects for other users.

Durability - Once an operation is complete, it will be preserved even if the machine or system experiences a failure.

These behaviours are mandatory to ensure transaction functionality.

If your operations are ACID compliant, the system will ensure your processing is protected against any failures.
