摘要
针对企业信息资源集成的现实需求,结合分布式数据的特点,建立了基于ogsa-dai的信息资源目录服务系统。在设计系统的体系结构和功能模块的基础上,给出了系统的运行过程;基于科技行业系统的异构信息资源实例,实现了该系统的相关功能及关键服务。研究和应用结果表明,该系统有助于梳理信息资源,能较好地应用于企业信息资源集成,具有较好的通用性。
Aimed at the real requirement of data integration,an information resource directory service system was constructed based on ogsa - dai while the characteristics of distributed data were considered. Based on the design of the structure and functional modules of the system,the system＇s work procedure was proposed. Furthermore,based on the technology of heterogeneous information resources system,the related function modules and key services were realized. The utilization results show that the system can be used in dynamic heterogeneous data integration to catalogue information resources, and the system has generality to some extent.
