A Study on Efficient Component Development with a Developer-Friendly Environment

Medical knowledge tends to change in its nature, and new medical services are frequently introduced. Component-based system design (CBD) is of great use for creation, maintenance, and update of such medical services, when a component implies a service. In particular, component composition is crucial in CBD to support better and complex medical services, while it requires the developer´s high competence and so is complicated and hard. In this respect, there is a need for tools to enable easy component composition. This paper proposes (1) a user interface (UI) helping the developer easily and intuitively organize and compose component elements in healthcare service systems, and (2) its related specification with XML. We will particularly call such a UI and its composition specification developer-friendly environment, The environment has been designed for the development of two vital sign oriented healthcare systems as a particular domain. Such healthcare systems have gradually gained their interests, as a new medical paradigm of ubiquitous healthcare demanding various vital sign data analysis is emerging.
