A process model for controlling and performing re-engineering tasks

We present a process model for controlling and performing reengineering tasks. This process model is based on a reengineering methodology, that regards the legacy system from the data oriented perspective and aims for decomposing and transforming it into an object oriented system along semantic units. The transformation from procedural to object oriented systems requires one to deal with system models at different abstraction levels which must be matched to each other. The object identification and the match are controlled and performed by two processes-the microprocess and the macroprocess. In order to find and process information with respect to an abstract object, the macroprocess initiates and coordinates a set of microprocesses that perform reengineering tasks with respect to a secluded functional and structural part of the IS
