摘　　要：整合政府、企业的信息资源,需要对信息资源整合的建模方法进行研究.为此提出了一种基于实体-关系-问题(E-R-P)的信息资源整合建模方法,介绍了实体、关系和问题三者之间的关系,以及E-R-P建模过程,并比较了E-R-P建模与传统ER建模的差别.结合信息资源整合实际项目,阐述了这种建模方法.该建模方法可为信息资源整合的系统实现提供方法性指导.In order to integrate the information resources in governments and enterprises, a research on modeling method of information resources integration is needed. Thus, a modeling method of information resources integration based on the study of entities-relations-problems （E-R-P） is proposed. The relationships among entity, relation and problem and modeling process are introduced. The differences between E-R-P model and traditional ER model are compared. The modeling method is expounded combining with the practical program of information resources integration. The modeling method can provide the methodological guidance for the systematic realization of information integration.
