Research Of Reusable Class Library For MIS

The purpose of software engineering regards software as the industrialized product which is designed efficiently and has high quality. Software Reuse has been proved to be an effective way to reach the purpose. In Software Reuse, the reusable class library is a widely-using and developed solution. The author researches Software Reuse in MIS from the view of reusable class library. The paper introduces the Software Crisis and the theory of Software Reuse, brings forward the necessity and the solution of applying the technology of Software Reuse in MIS. The paper introduces the theory of Object Oriented technology and design pattern in brief and discusses their application in Software Reuse.Under the ground of the deeply researching on the essentials of Information System, the paper puts forward the model of common structure of Management Information System and analyzes it in-depth. Based on the common structure, this paper abstracts the reusable class library for Information System and elaborates the structure and design idea of the reusable class library. Then the paper describes the implement of some typical reusable class. In the end, the paper introduces the actual application of the reusable class library in the Postgraduate Information System.
