1. Explain the concept of an "atomic transaction."

Question

Chinni Guna Venkata Prasanth · Accepted Answer

In database the word atomic transaction we mean either:

All the individual operations goes through

Or no transactions/operations occur at all.

The concept of atomic transaction is to ensure that all the operations users make are finished successfully. If in case any operation is not gone through then the database is rolled back to the state it was before the commit being initiated.

This is crucial to avoid situations where a transaction was only partially completed, leading to an unclear overall state, as a result of crashes or outages. You cannot precisely determine how far along the process was prior to the transaction being interrupted if a crash happens during a transaction that lacks atomicity. By employing atomicity, you can make sure that either the entire transaction is successful—or that none of it was—or that it was unsuccessful in some way.
