Estimating the term…
A system and method for selectively retaining object history using a series of snapshots from a database is claimed. Rules are established for a database file or table to determine snapshot triggers. When a rule is triggered by an event, a snapshot is taken of a predefined set of database data. The snapshot is stored in a separate data area, such as a database table. Snapshots are queried and analyzed to determine historical trends. In addition, snapshot data can be overlaid onto the current database data in order to view changes in the data and also to facilitate record rollback using the snapshot data. When a rollback is requested, the current database record is copied to a new snapshot record and one of the snapshot records is overlaid onto the current database record creating a new database record. A transaction log is also maintained to record details regarding snapshot processing.
