Research On Component-based Domain Application Framework

Software reuse is one of the important fields of computer research.,integrating with software reuse,distribute computing,CASE and enterprise application programming ,CBD(Component Based Software Development) becomes An effective way to increase productivity and quality of software for their distributiveness ,high scalability ,deployability ,effectiveness and easy maintenance . Today those technologies are used in such fields as User Interface Design ,but are seldom applied in large project ,and research on domain-specific application framework is still in the early phrase.This paper discusses in detail basic attributes of component ,component model ,component browse ,component evolution and CBD ,On the basis of the research establishes a Component-based Business Application Framework-CBAF . then we analyzes the framework with the technology of role modeling and design patterns,and get the abstract pattern of data accessing.Finally ,based on CBAF ,with the technology of double project,this paper presents a medicare insurance domain application framework that can fulfill the integration requirement in distributed heterogeneous environment and unify Client/Server application and Browse/Server Application ,and discusses the key technologies related to this model.
