面向服务的经济预警系统研究

A service-oriented economic early warning system

针对当前经济安全预警领域中计量经济模型集成和重用困难,以及数据采集与传递中存在的异构数据平台、采集不全面、网络流量大、原始数据没有被有效利用等数据效率瓶颈问题,采用面向服务的体系结构(SOA)构建我国宏观经济安全预警系统,并利用Web服务集成数据接口,为系统提供统一的数据采集服务,实现异构数据平台和计量经济模型的有效整合。

The further development of economic safety early warning system is severely yoked by many negative factors,such as the difficulty of model integration,heterogeneous database platform in data collection and trans- ferring, incomplete data collection and the incompetence of visual display of early warning effect. Aimed at the above defects, the paper proposes a new method of economic safety early warning system adopting service-orient- ed architecture based on Web service. This system applies a standardized interface to make each component work cooperatively and realizes the integration of heterogeneous database platform and econometric model. Thus the problem of data integration is solved successfully.
