Web Environment, Procurement Of Component-based Information Management System Research And Development,

With the development of Internet/Intranet technology, it is popular that the enterprises adopt web-based purchase system to commit E-Commerce. Furthermore, It is easy to develop, manage and maintain the web application. But there are also some problems, such as the efficiency of the system, the difficulty to reuse the code. In order to solve these issues, we study the development of web-based purchase system using reusable Components in this paper.Firstly, we give the definition of the component, compare the component criterion of COM, CORBA and EJB, and put forward the application structure. Especially, the component based on COM+ criterion is studied. Secondly, we establish the model of web-based purchase system, design the components and the interfaces of components. Last, we develop the system based on the B/S mode. We make use of Delphi6.0 as the development tools, Microsoft SQL Server7.0 as the database management system.
