The approach supports dataflow process definition, consequentl y it supports business process reengineering. The approach supports integration system’s batch deployment, it has provided a way for large-scale different plac e’s database application integration.

Key words: integration automaton, database, business process modeling, data d riven, data replicate, middleware
