【摘要】 决策支持系统(DSS)是主要面向企业的中高层领导,用于帮助领导者进行事件决策和趋势分析的应用。针对这些需求,文中将介绍一个用于银行业的决策支持系统的开发方法。本系统遵循J2EE标准,并在3-层结构的基础上再一次解耦,使每层的功能更加单一化。在系统的核心部分采用Java平台的组件技术,设计出一个可供决策者方便地构建、执行、存储、扩充模型并且可移植的模型系统。而数据访问接口则是整个中间层可移植的基础。实践证明这种开发方法具有开发周期性短、可维护性强等特点。更多还原

【Abstract】 T:Decision support system is an application which is mainly designed for the middle or high layer leader in enterprises to making decisions and analyzing trends.This paper introduces a development method of a DSS used in banking.The system is based on J2EE and makes the function in every tier more singular by layering the 3-tier architecture.In the kernel part,adopt component technology to design a module system which can be constructed,executed,stored,expanded and transplanted conveniently.The data access interface is the base for the transplantability of the whole middle tier.It has been proved in practice that this development has many advantages,such as short development cycle and strong fine maintainability.更多还原
