Commit (data management)
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. A "commit" is an act of committing. The record of commits is called the commit log. Data management. A codice_1 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 codice_2 (or codice_3, depending on the database vendor) statement, one or more SQL statements, and then the codice_1 statement . Alternatively, a codice_5 statement can be issued, which undoes all the work performed since codice_2 was issued. A codice_1 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.
