This property ensures that multiple transactions can occur concurrently without leading to the inconsistency of the database state. Inconsistency occurs in case T1 completes but T2 fails. The total amount before and after the transaction must be maintained. It refers to the correctness of a database. This means that integrity constraints must be maintained so that the database is consistent before and after the transaction. Therefore, the transaction must be executed in its entirety in order to ensure the correctness of the database state. This results in an inconsistent database state. If the transaction fails after completion of T1 but before completion of T2.( say, after write(X) but before write(Y)), then the amount has been deducted from X but not added to Y.
