基于Web的证券分析决策支持系统

基于Web的证券分析系统是目前的发展趋势.该系统不仅具有业务数据库,并引入了多维数据模型和广义模型库.其系统结构采用数据层、逻辑层、应用层3层B/S结构模式,通过Web服务器与Internet建立联系.用户可以利用多维数据模型,在业务数据库基础上,从多维角度对数据进行分析和提取.广义模型服务调用广义模型库中的模块,对多维数据进行分析和转化,从而获得最终的决策信息.同时也可从Internet网上获得所需信息.这种面向大众的证券分析决策支持系统.适应分布式异构系统的要求,有较好的移植性和可扩展性.

Web-based Decision Support System for Security Analysis

The developing Web-based security analysis system is a developmental trend at present. There is not only operation database, but also multi-dimension data model and generalized database model in Web-based security analysis system. 3 layers B /S structure modes as data layer, logical layer and application layer was used in the structure of the system, the contact with Internet was established by passing Web-server. Based on operation database, data was analyzed and accessed with multi-dimension data model. The module of generalized database model was played in generalized model service, and multi-dimension data was analyzed and transferred, so decision information was finally obtained. At the same time, much needful information was obtained from Internet. The decision support system for security analysis applies to the requirement of distributed Heterogeneous system, and has better transplantable property and expansibility.
