In computer science and data management, a commit is the making of a set of tentative changes permanent, marking the end of a transaction and providing Durability to ACID transactions.
The transaction, commit and rollback concepts are key to the ACID property of databases.
[1] A COMMIT statement in SQL ends a transaction within a relational database management system (RDBMS) and makes all changes visible to other users.
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.
