【摘要】 需求变更致使系统进行连锁变动,增大了系统修改和维护的复杂度。本文提出元数据模型概念,通过对系统基础数据建模,开辟一种新型的开发模式,提高了系统开发速度,并且能够快速的应对需求变化。文中主要介绍元数据模型的设计思想以及该模型在监测系统中的具体实现方法,在实际应用中得到了很好验证。更多还原

【Abstract】 The modifications of system demand make the complexity of the modification and maintenance of system increased.In this paper,we propose a definition of metadata model,and open up a new development pattern through modeling the base data of system.The speed of system development is increased and the changes of system demand can be managed speedily through our metadata model.The design method of metadata model and the implement of the monitoring system are described detailed in this paper.The effect of the metadata model is validated in the real application.更多还原
