Remodeling of legacy systems in health care using UML.
Research projects in the field of Medical Informatics often involve the development of application systems. Usually they are developed over a longer period of time, so that at a certain point of time a systematically planned reimplementation is necessary. The first step of reimplementation should be a systematic and comprehensive remodeling. When using UML for this task a systematic approach for remodeling activities is missing. Therefore, we developed a method for remodeling of legacy systems (Qumquad) and applied it to DOSPO, a documentation and therapy planning system for pediatric oncology. Qumquad helps to systematically carry out three steps: the modeling of the current actual state of the application system, the systematic identification of weak points and the development of a target concept for reimplementation considering the identified weak points. Results show that this approach is valuable and feasible and could be applied to various application systems in health care.
