Case Study: Dynamic Configuration Management for HIEs Client Requirements
shared across the participating systems. CitiusTech also analyzed several existing technologies to identify the mechanism that would be used to share the configuration information.
Client is a leading Health Information Exchange (HIE) application vendor providing interoperability solutions to share clinical data over distributed networks. CitiusTech was selected to develop a module for real-time configuration of systems to facilitate information exchange using the XCA and XDS IHE profiles.
Development The CitiusTech team designed the overall solution with the following features: • Created a centralized repository for maintaining configuration information • Identified specific transactional information which was required for IHE profiles supported by the system • Used XML based messages and web services as the underlying technologies to provide access to the configuration information • Created a web-based UI which provided real time access to the configuration information with a secure login • Ensured that the configuration data was accessed and shared securely to prevent unauthorized access
Some of the key requirements for the real-time configuration module were: • To be platform independent in order to build a solution which uses open standards like XML and web services (HTTP) • To be usable on older systems • Adaptable to newer technologies, while maintaining backward compatibility with the existing systems • Support distribution of configuration information to enable participating systems to access the information through an automated mechanism Initiating Community
