摘　　要：同构是相对的,异构是绝对的。异构性在信息系统中普遍存在,它是信息共享以及信息系统之间互操作的主要障碍。该文探索了信息系统异构性的合理化描述,给出几种定义异构性的方法。另外,异构性和任何事物一样,存在积极和消极的两个方面。论文研究并指出开发和利用异构性可增强信息系统的功能,屏蔽和抑制异构性可消除负面影响,从而拓宽信息系统的互操作和可用性。以上研究工作尚处于起步阶段,为深入探索异构性的规律及解决方案奠定了基础。The homogeneous is relative while the heterogeneous is absolute.There is heterogeneity in common among information systems ,which is a main obstacle for information systems to share information and to cooperate well.This paper inquires the sound description of heterogeneity for information systems ,and presents several approaches on definition of heterogeneity.Moreover,like everything,heterogeneity has two positive and negative aspects.After studying,the paper points out that the capability and power of information systems can be strengthened by exploring and making use of heterogeneity,and its bad effects can be eliminated by hiding and controlling heterogeneity,so that information system can be broadened in interoperability and usability.Such researches are just in infant ,but lay some foundation for deeply inquiring heterogeneity law and its solutions.
