COMMIT

COMMIT is a fundamental operation in both version control systems and database management systems. In version control systems such as Git, a commit represents a snapshot of changes to the repository at a specific point in time. When a user commits changes, they create a new revision that includes a unique identifier, a timestamp, and a message describing the modifications. Commits form the history of a project, allowing developers to track changes, revert to previous states, and collaborate effectively.

In database management systems, COMMIT is a transaction control language command that permanently saves changes made during a transaction to the database. When a transaction is committed, all modifications become visible to other database sessions and are guaranteed to be durable even in the event of system failures. The COMMIT operation is typically paired with ROLLBACK, which undoes changes if an error occurs during a transaction. Both concepts are essential for maintaining data integrity and enabling reliable software development workflows.
