Question
Which database management system feature helps ensure
that all transactions are completed successfully and consistently?Solution
Atomicity is a property of database transactions that ensures each transaction is completed entirely or not at all. This means that if a transaction cannot be completed successfully, it will be rolled back to its previous state, maintaining the database's integrity and consistency. a) Data Integrity ensures the accuracy and consistency of data but is not specifically about transaction completion. c) Concurrency Control manages simultaneous transaction execution but does not guarantee complete transaction success. d) Durability ensures that once a transaction is committed, it is permanent, but it does not address incomplete transactions. e) Consistency ensures that transactions lead to a valid state of the database but does not handle incomplete transactions directly.
