| With the increase of software system scope and complexity, the selection and statements of the system architecture has become more important than the selection of special algorithm and date structure. Software architecture has become an important domain of the software engineering. Firstly the thesis introduces the conception of software architecture, the research direction of this domain. The thesis has mainly researched and analyzed computer examination, and based on the Business Bus architecture model. We went along with some detailed architecture designs. These architecture designs were focused on Domain Specific which included the existed dynamic system expansibility and the compatibility of the edition. The practices proved that this systematic architecture accommodated well to the characters of computer examination. It can make the software architecture clearer and make the system more easily to be developed, expanded and serviced. All these showed that this Business Bus has so much practical value. |
