Software Component Library Based On The Ado Technology Development Research

When the Pervasive Computing age is coming, the embedded system will be more and more important. Productivity and quality of the embedded software are crucial for success of the embedded system. Component-Based Software Development (CBSD) is one of the most effective methods for the productivity and quality of the embedded software.It is important to establish the componet library which classifies and manages the components. We should research the component library management system for embedded component based on componets software development, in order to make the embedded sortware development become the pipelining. In those papers, component-based software development and components, information management will be the research objects. Deep theory research and practical using about the components in the embedded software development platform, compnonent library and information management in particular domain will be discussed.CBSD is introduced. Then the component libraries and retrieval method are analyzed, then several software architectures are compared and"Plug and Play"characteristic is used as infrastructure for constructing the embedded software development platform.The classifying strategy for universal components, appropriative components (such as Embedded OS and middleware) and CASE tools is discussed. And then, the classification methods for embedded components and the corresponding libraries management strategies are presented based on the analysis described above.Finally, using a'Platform for Vehicle electron'as an example, an Information Management System supporting management of components and development information targeted for embedded software development process is designed and implemented, and its effectiveness is evaluated by prototype verification and corresponding testing, which may benefit software development in efficiency and quality.
