Usage of XML technology in electronic health record for effective heterogeneous systems integration in healthcare

A virtual patient record is an ideal electronic health record (EHR) that is decentralised and contains heterogeneous clinical data. Extensible markup language (XML) is a web standard that has become the major driver towards heterogeneous systems integration for any industry solution. This work focuses on creating an XML schema that operates as an interface between different heterogeneous patient record structures. The XML schema structure is based on standards such as HL7 and DICOM modelled with UML metadata techniques. The technological platform used to test this XML schema is by implementing various healthcare scenarios and XML-based technologies.
