METHOD AND APPARATUS FOR CHANGE DATA CAPTURE IN A DATABASE SYSTEM

摘要

A method of change data captured is disclosed, in which modifications made to on-line transaction processing (OLTP) tables (e.g. inserts, updates, and deletes) are maintained in a database object, referred to as a change table. The change data in the change table is then made available to analysis applications in a controlled manner, such as in accordance with a publication-subscription model.
