研究了基于J2EE模式的决策支持系统的模型库构建及管理方法。阐述了J2EE模式下模型的表示方法,结合一个决策支持系统实例阐述了如何利用抽象工厂创建模型,在此基础上讨论了模型库的管理机制及调用方法,最后给出了一种模型库与数据库的常用连接方法。结果表明,基于J2EE的模型库构建及管理方法较一般的面向对象的模型库构建及管理方法有明显的优势。用J2EE来开发模型库系统是一种方便而快捷的方式。

Research on Model System Design Based on J2EEZOU Xiao-tian (School of Management,Wuhan University of Technology,Wuhan 430070,China)Based on J2EE design pattern,the paper discussed and solved several key problems on model system development,including creating models,managing a large quantity of model instances and connecting to a database.The results show that the development of model system under J2EE design pattern has a lot of advanteges than other object oriented design patterns.DSS;model;model management;J2EE
