基于国际标准的企业信息资源目录及ETL模型研究

Research on Enterprise Information Resources Directory and ETL Model Based on International Standard

虽然国内多个部门和组织建立了为自己所用的信息资源目录,但企业各部门间还没有建立完善共享的企业信息资源目录。在企业信息领域的"信息孤岛"问题的基础上,探讨如何实现企业部门间信息共享。结合ISO/IEC 19763中的信息模型注册规范、映射信息注册规范,结合信息资源目录的特性、编目原则及其数据模型,设计了基于信息资源目录的ETL技术模型,构建了基于信息资源目录的企业信息资源共享系统架构。结合ISO/IEC 19763中的信息模型注册规范、映射信息注册规范,提出了基于企业信息资源的共享模型,打破各异构系统之间的隔阂,实现对企业信息资源的统一化管理,使企业间信息资源达到共享的目的,为企业人员和公众用户提供全面的检索以及获企业信息资源的管理及服务体系。

Although several domestic departments and organizations have established the information resources directory for their own use,but there is no perfect-shared information resources directory between various departments of enterprise.On the basis of＇Information island＇ problem in the field of enterprise information,it discusses how to implement information sharing between the corporate sectors.The innovation of this method is that it combines the registration specification of information models and mapping information in ISO/IEC 19763,integrates the characteristics,cataloguing principles and data model of the information resource,and then it designs the model of ETL technology based on information resource directory to build up the enterprise information resource sharing based on the information resource catalog system architecture.Combining the registration specification of the information models and mapping information in ISO/IEC 19763,it proposes the shared model based on the enterprise information resource,break the barriers between the heterogeneous system,and realize the unification of enterprise information resources management.It helps the enterprise to achieve the purpose of sharing information resources,and provides the enterprise staffs and the public users with the management and service system for comprehensive retrieval and obtainment of enterprise information resource.
