Research On A Reusable E-business System Based On Components

With the development of computer network and software technologies, e-business has emerged and developed, and its prosperity put forward higher needs for more advanced techniques. So how to develop the e-business application quickly and easily is a project that needs to be resolved immediately. Traditional methods of software development have not satisfied the demands, so this dissertation does research on the reusable e-business system based on component technology.Based on Component-Based Software Development (CBSD), the effects of middleware in system architecture are analyzed, and then the promotion of component technology to middleware is illustrated. Finally the development model of middleware based on components is concluded, and a middleware framework of e-business system based on components is proposed by the author in order to implement the framework reuse.The author makes use of some techniques to implement a system based on J2EE application model. MVC hierarchical model provides an academic basis for abstracting the object models; Using UML components to create application models during system analysis and design, and describe controlling logic, business logic and data logic components; and Servlet, JSP, EJB provides methods for implementing the components. Thus the codes are implemented to be reusable.It is concluded that the research on reusable e-business system based on components is not only helpful to improve the productivity of application development, but also make the application system reusable and maintainable. So it is very important in both theory and application for us to do the research.
