For the revision control concept, see Commit (revision control).

In computer science and data management, a commit is the making of a set of tentative changes permanent. A popular usage is at the end of a transaction. A commit is an act of committing. The record of commits is called the commit log.



Data management


A COMMIT statement in SQL ends a transaction within a relational database management system (RDBMS) and makes all changes visible to other users. The general format is to issue a BEGIN WORK statement, one or more SQL statements, and then the COMMIT statement. Alternatively, a ROLLBACK statement can be issued, which undoes all the work performed since BEGIN WORK was issued. A COMMIT statement will also release any existing savepoints that may be in use.


In terms of transactions, the opposite of commit is to discard the tentative changes of a transaction, a rollback.
