Abstract:
A method and software for change data capture are disclosed, in which change data is extracted from a recovery log and stored in a database object. The change data indicates what modification has been performed to a source object on the OLTP system. In some embodiments of the present invention, a database statement may be generated and executed to extract and load the change data, and the recovery log itself may be shipped from an OLTP system to a staging system.
