Research And Achievement Of Universal MIS Based On Component Reuse

Due to the rapid development of computer technology, and especially of network technology , the direction of integratize , intelligentize, networktize and distributed are the inevitable trend in Information System . Simultaneously ,It has prodigious changed in aspect of dimensions, framework, function administrative levels and design realization compared with conventional stand-alone application system. In the face of increasing isomeric-hardware environment and varous OS along with communication stage .It is very difficult to develop an integrative MIS gave attention to validity, transportability and correctness . At the same time, development model based on software reuse gradually become main technology for Universal MIS .On the task of "material MIS", the emphasis of paper is put forward a design model of "based on software reuse" to construct Rebuilding System and provide structure-reuse of span-Application System by combining software-reuse with Object-Oriented technology . All kinds of technology including software component, middleware , heterogeneous database integration , multi-tiered architectures, aredescribed in detail . In addition to ,the paper has a discussion on building of universal MIS Domain component, emphasizes that the key of using software-reuse is the reuse combine technology of software component . Finally, on the basis of the design model ,we achieve an specific MIS based on component .Even more request for universal MIS are brought forward by exterior dynamic environment such as user requirement levity and development environment levity . Presently ,MIS Developing Mode has localization for its only pay attention to transaction disposal. The main purpose for paper why propose Rebuilding Design Conception is remedy this limitation, then design relevant framework and analyse problems including rebuilding design of DataBase . dynamic Data Window construction and so on. After that ,given corresponding resolve way.
