  1. The structural framework of the on - line test system has been built in the paper, based on j2ee and xml. uml is integrated into the development of web application in virtue of rose to get visual system model. the system requirements and design models are defined by uml diagrams such as use case diagram, class diagram, sequence diagram, collaboration diagram, component diagram, and deployment diagram. web pages, component objects, data tables and databases are all regarded as a class or an object. the modeling process bases on the views of real world. the design and development process is established according to the views of software engineering. the online examination system which bases on j2ee can fully use the jsp 、 javabean 、 servlet 、 xml, flexibility of three - tier model to optimize the system performance and to enhance. the development value

    同時藉助rose工具將uml語言和web應用開發結合起來,進行可視化建模,利用uml的用例圖、類圖、時序圖、合作圖、組件圖和部署圖等,定義系統需求,描述系統設計,將web頁面、組件對象、數據表和數據庫都作為類或對象,按照真實世界的觀點進行建模,依據軟體工程學的觀點制定設計開發步驟。本系統以j2ee體系結構為基礎,充分利用jsp 、 javabean 、 servlet 、 xml組件和三層模式的靈活性來簡化開發過程,優化系統性能,從而提高了系統的開發價值。
