ABSTRACT:
A technique for maintaining the integrity of data maintained in an object in a persistent store of objects. When a modification event is initiated during a transaction to modify an object, a copy of the object is created. Modifications are made to the copy of the object, and the original object remains available to be accessed with its original value. The modifications to the copy of the object can be reviewed, or further modifications can be made to the copy before the modifications are committed and the changes to the copy applied to the original object and thus available to all users of the persistent store. Alternatively, the modification event can be canceled prior to commitment and never be made available via the persistent store.
