Consistency: A transaction which proceeds to the valid state of data or if any failure occurs, it returns all the data to its state at the point where the transaction begins. It stands for correctness and ensures that any transaction will carry the database from one valid to state to another valid state. Application programmer is responsible for maintaining the consistency.
