Undoing a change in such a way that the net effect is that no change in the state of an application or its data can be perceived. In the context of DBMS, this means to abandon a transaction and restore the previous state of the database. In the context of exception handling, this is normally a requirement of cleanup after an exception has occurred. See also: transaction commit leave cleanup
Rollback refers to an agreement among Uruguay Round participants to dismantle all trade-restrictive or distorting measures that are inconsistent with the provisions of the GATT. Measures subject to rollback would be phased out or brought into conformity within an agreed timeframe, no later than by the formal completion of the negotiations. The rollback agreement is accompanied by a commitment to "standstill" on existing trade-restrictive measures. Rollback is also used as a reference to the imposition of quantitative restrictions at levels less than those occurring in the present. See: Standstill.
Allows changes and updates that have not been committed to return to the previous state.
The process of restoring data changed by SQL statements to the state at its last commit point. See also point of consistency.
A commitment to phase out all trade restrictions or policies that distort trade or bring them into conformity with GATT rules. Under the rollback commitment made at the outset of the Uruguay Round, participants are not to seek compensatory concessions for rollback measures.
The process of resetting a system back to the previous software state. A rollback can include some or all of the operating system, patch, and application software. For example, you can rollback a system from HP-UX 11.0 to HP-UX 10.20 or from patch level 2 to patch level 1. This process requires good backups or an archive created with the Ignite-UX make_recovery tool.
The phasing out of measures that are not consistent with an agreement. In the Uruguay Round, the agreement to remove all GATT-inconsistent trade-restricting and trade-distorting measures by the time negotiations were completed. See standstill.
A command that removes all changes since the last Commit or Save. Rollback is the same as Revert to Saved in other applications. On validation, application, and inquiry forms, Rollback returns the cursor to the first enterable field on the form. On query forms, Rollback returns the cursor to the first enterable field on the calling form. Rollback is also referred to as Clear Form.
Replace or phasing out of trade restrictive and discrimminatory measures. Specific commitments can schedule time limits for the future rollback or elimination of measures
A return to a previous stable condition, as when the contents of a hard disk are restored from a backup after a destructive hard disk error.

A method used by Windows Installer to recover from a failed install. Similar to the rollback definition used in SQL. Consists of storing files, folders, and registry settings marked for deletion in a hidden temporary folder. If a serious error is encountered during the installation of new software, the files, folders, and registry settings are returned to their previous settings (as if the attempted installation never happened).

In database technologies, a rollback is an operation which returns the database to some previous state. Rollbacks are important for database integrity, because they mean that the database can be restored to a clean copy even after erroneous operations are performed. They are crucial for recovering from database server crashes; by rolling back any transaction which was active at the time of the crash, the database is restored to a consistent state.
