【摘要】 针对电子政务中信息资源元数据的表示问题,在研究实体—关系—问题(E-R-P)建模体系的基础上,以数据仓库数据模型的星型模式为例,给出了基于E-R-P建模体系的政务信息资源元数据表示模型及相应的系统概念模型。实践证明,该模型能较好地实现政府信息资源的高效发现和共享。更多还原

【Abstract】 To solve the problem of metadata representation for E-government information resources,this paper proposes entity-relation-problem(E-R-P) modeling system for metadata modeling and offers metadata representation model based on E-R-P modeling system.It takes metadata expression of star schema model of data warehouse as example.Corresponding system conceptual model is also proposed.And the practice proves the improvement of the model.更多还原
