DataServer: An XML-based Data Gateway for Clinical Information

This research detailed development of an electronic infrastructure that established a single access point for patient information using XML as the basis for representing queries and results to and from clinical data sources. The variety of current medical standards has resulted in a highly heterogeneous, distributed data environment, making it difficult to aggregate patient information into one view. The proposed system works on two levels: 1) intra-site, mapping data sources in a single institution through explicit mapping of data sources into an XML format; and 2) inter-site, which propagates queries to multiple sites to retrieve a single's patient medical record.
