Research Of Component Reuse In CED Domain

Software component and distributional object technology has great influence to the traditional development methods. With their distribution and openness, deploy ability, high efficiency, easy maintenance, etc, they are considered to be the effective way to solve the software crisis Together with component reuse. At present, because overemphasized on the generality of technology, the existent study made these productions cannot obtain ideal effect on special domain.At present, in College Education Domain, national each university's each department all respectively uses own subsystem, which causes the identical information is not to be mutually inconsistent, and is difficult to be exchanged, and the useful information cannot promptly share, statistical analysis. Because the development of CED system always follow the stereotype of developing special systems aim at a single corporation, each time we have to develop new CED systems from scratch, which cause difficult development, long period, high cost, and the system can hardly reconfigurable and be reused. It blocks the development of CED system.Based on this present situation, the paper proposes the idea to develop component-based CED system. The research and the discussion of the CED domain applies the component technology and the domain project method, uses the software product line technology to carry on the development of educate the domain application system of the university. This paper has analyzed the component technology and the domain project method, discussed component-based software development technology, has conducted the research to the CED domain component and the component management. Study how to extract the soft component from the CED domain. Apply the domain project to the CED system development, establish the CED domain model, then unify the UML model technology, extract and realize partial the CED domain components. This kind of component is extremely useful for developing the CED domain application system, and it may greatly reduce the work load, reduces the development cycle, and enhances the system the quality.
