Over the years EMR (Electronic Medical Record) has grown exponentially, as a result health care providers have been left to deal with increasingly complex software architectures. In order to meet the ever changing business needs, EMRS’ architectures have evolved through the years, from the standalone applications to web based applications. But, these myriad of architectures so far are inflexible, difficult to integrate with other applications, and unable to unify business processes, such as clinical data sharing among unaffiliated health care providers. Lack of standard-compliant software architectures among multiple EMR vendors’ products has still continued to be significant bottlenecks, such as interoperability, reusability, and integration. A study of these bottlenecks is therefore essential to address many fundamental architectural issues. Principally, this study will investigate the issues pertaining to the traditional EMR architectures and proposes such ideal distributed software architecture, Service Oriented Architecture (SOA), that support the integration and interoperability of loosely coupled subsystems and software elements as a replacement for traditional EMR architecture.
