Componentization method for reengineering legacy system
First Claim
Patent Images
1. A componentization method for reengineering a legacy system, comprising:
- a) a planning phase of establishing a componentization strategy and a process plan of the legacy system for the reengineering;
b) a reverse engineering phase of analyzing program information of the legacy system and recovering functional information and architecture information;
c) a componentization phase of extracting components from the legacy system, establishing target architecture, and designing and implementing components to comply with the target architecture; and
d) a delivery phase of delivering transformed components which a user has approved after a forward engineering method.

Abstract
The present invention proposes a Magic and Robust Methodology Integrated-Reengineering (MaRMI-RE), which is a reengineering methodology defining a process including procedures and techniques for a componentization of legacy systems and work products generated during the process. A continuous evolution model for the legacy systems proposed in the present invention enables the legacy systems to be systematically transformed into component systems capable of smoothly complying with new requirements, thus maximizing productivity and efficiency of the legacy systems with respect to potential business and system change requirements.
