Abstract:At present, the information system has been widely used in various fields, along with the constantly changing of the application environment and the needs of the user, developed products with a high intensity of portable and scalable function are required to respond to that. In accordance with the drawbacks of traditional information systems development methods, this paper mainly puts forward the. NET platform development framework based on hierarchical component. In the integrated platform of Rational XDE and. NET, with the function of Synchronous development, the components can be designed with the operations of modeling, extraction, and encapsulation. Also, taking student management information system of vocational colleges as a development example, this paper describes the main steps of the development approach of part of modules and analyzes their advantages. The example verifies that the system with the development methods described has a portable and scalable function.
