基于实体连接的信息组织技术

企业在实施信息化过程中，由于未规划系统和信息变动因素等存在，使得企业不得不改变原有信息系统的数据模式，但现有的信息组织技术及理论却难以解决未规划系统和信息变动对数据模式无损依赖性和无损连接性的影响，极大地影响了企业实施信息化的进程，也造成了资源浪费。针对以上问题，以关系数据理论为基础，借助E—R语义建模模型，提出了一种基于实体连接的信息组织技术，该信息组织技术具有良好的扩展性和柔性，能够适应企业信息的变化和调整。

Information Organization Technique Based on Entity Linkage

In the course of Information Engineering of enterprises, because of the existence of unplanned system and information verification, enterprises have to change primary data model of the information system. But existing information organizing technique and theory can not solve the influence that unplanned system and information verification impact on preserve linkage and preserve dependency of the data model, and this has great effect on the process of Information Engineering. Aiming at solving the problem mentioned above, on the basis of Relation Data Theory and making use of E-R model, the paper puts forward an information organization technique based on entity linkage with well expandability and flexibility. The technique can adapt to information verification and adjustment of enterprise.
