D) Transaction has two SQL requests, both successfully complete, the data is then committed.
Explanation: Atomicity requires that all SQL requests in a transaction should be fully completed and if not, the entire transaction should be aborted. The transaction should be viewed as a single logical unit of work that is indivisible.
A transaction has two SQL requests both successfully completed and then the data is committed. Option (d) is correct.
What do you mean by Transaction?An executed contract between a buyer and a seller to trade goods, services, or financial assets in exchange for money is known as a transaction. The phrase is also frequently used in business accounting.
Atomicity mandates that each SQL request inside a transaction be fully finished; otherwise, the transaction must be canceled. The transaction should be seen as a single, indivisible logical unit of work.
A database's atomicity assures that it adheres to the all or nothing principle. In other words, the database views each transaction as a single, complete entity. As a result, when a database processes a transaction, it either executes it in full or not at all.
Therefore, Option (d) is correct. A transaction has two SQL requests both successfully completed and then the data is committed.
