TRANSACTIONAL CONSISTENCY CHANGE TRACKING FOR DATABASE

摘要

PROBLEM TO BE SOLVED: To maintain the consistency of source data with destination data during transactional replication by use of a change tracking technique. SOLUTION: A first functional characteristic is that the technique is a transactional database replication technique. A second characteristic is that the technique supports an incremental tracking of transactional states of the source system. A third characteristic of the technique is that it utilizes triggers to track changes while satisfying the first two characteristics. COPYRIGHT: (C)2006,JPO&NCIPI
