Medical Insurance Management Information System Software Re-engineering

Re-engineering to an old Medicare Management Information System is discussed in this paper.The trend of Medicare Management Information System is first analyzed in this paper. The problem of the Medicare Management Information System in which I participated developing is also discussed. Then the requirement of Re-engineering to partial function of the old system is analyzed in paper.Three main technologies are discussed in this paper: Re-engineering, Rational Unified Process and Distributed Object Technology, which provides the technical possibility of Re-Engineering to the old system. With reference to Rational Unified Process, this paper designs a process which is fit for the Re-engineering to the old system.With the help of Forward Engineering, how to turn a traditional Client/Server Architecture System into a Multi-tier Distributed Architecture System, and how to turn a structural Architecture System into Oriented-Object Architecture System is also discussed this paper.
