Restoring records using a change transaction log
Abstract:
In one embodiment of the method, a first transaction is generated for deleting a record from a table of a database. In response the record is deleted from the table. Further in response to the generation of the first transaction, a copy of data of the record is stored in an entry of a transaction log before the record is deleted from the table. An instruction is then generated, and in response the record is restored to the table after the record is deleted, wherein the record is restored in the table using the copy of the data in the transaction log entry.
