Question

Describe transactional consistency in your own words

Answer 1

Solution:

Transactional consistency:

This requires the data to be consistent when the transaction is being performed.

The consistency property is one of the rules among ACID properties of the transaction.

The ACID rules are Atomicity, consistency, isolation and durability.

Consider the situation where the funds are being transferred from one account to another.

The consistency property states that the total amount in both the accounts must be equal before and after the transaction.

The amount must be debited from one account and be credited successfully into another account.

So this ensures the total value i.e., the sum of amounts from both the accounts remain the same before and after the transaction.

This ensures the consistency of the transaction.
