数据模型设计是数据仓库建设的核心,提出一种医院数据仓库数据模型的设计方法。以某一三甲医院的HIS数据为背景,采用数据驱动的手段,结合医院的需求,提出了医院数据仓库的三层数据模型,概念模型、逻辑模型、物理模型,并完整地给出了每个模型的具体的设计和主要内容。设计并实现了医院数据仓库的数据模型,并结合医院具体的数据给出了相应的实例。此医院数据仓库的三层数据模型易于理解和实现,为医院数据仓库设计最终完成提供了基础。
Data model design is the core of building a data warehouse,present a kind of design approach of hospital data warehouse's data model.With a top three hospital HIS data as the background,using datadriven tools and combined with the needs of the hospital,the text proposes the hospital data warehouse's three-tier data model of conceptual model,logical model,physical model,and completes each model given the specific design and main content.This hospital data warehouse's three-tier data model is easy to understand and realize and provides the basis for the design finalized.
