Towards specialised middleware for healthcare information systems

Middleware is now a commonly used expression and anyone building distributed applications is referring to ‘middleware services’. Nevertheless this notion lacks of sound theoretical foundation. This paper tries to clarify the relationship between the components of distributed environments, especially in healthcare and to establish some classification aiming at gaining a common understanding of the functionality and interdependency of the existing modules of distributed environments. A case study is presented and the potential benefits of using a middleware approach are discussed.
