This paper presents a research on the data model of EHR storage, focusing on solving the complex and abstract information model and data types in HL7 V3（Health Level 7 Version 3.0） as well as HL7 localizing storage. Using health-care information exchange and sharing standards may settle the problem of interoperability between heterogeneous systems. HL7 is the most widely accepted and used standard. HL7 standardizes the information format in the process of transmission. Nevertheless, it can not guide the storage of health-care data directly. HL7 V3 developed an abstract information model-reference information model （RIM） and data types in it are complex. In this paper, we propose an approach on converting from the abstract HL7 V3 information model to the relational data model. Our approach resolves RIM＇s complex relationships and its data types and localizes the HL7 V3.展开更多
