Abstract
The disclosed embodiments provide a system for updating database records while maintaining accessible temporal history. The system operates by receiving a request, at a database, to select a specific instance of a record from the database at a specific point in time. In response to the request, the system reads an instance of the record from a snapshot of the database, wherein the snapshot of the database was made prior to the specific point in time. Next, the system loads one or more deltas associated with the record from the database, wherein each delta in the one or more deltas comprises the difference between a new state of the record and a prior state of the record. The system then chronologically applies the one or more deltas to the instance of the record to create the specific instance of the record. Finally, the system returns the specific instance of the record.
