ANALYZING AND DEVELOPING OBJECT-ORIENTED MEDICAL APPLICATIONS WITH HELIOS

The HELIOS project promotes systematic reuse of existing software in a valuable methodological context. In order to reach this goal, the Ana lysis and Design Development Environment (ADDE) has been realized as a HELIOS component. This component includes the Analysis and Design sub -component (ADT), which supports the Rumbaugh's object-oriented method ology and the Insertion Retrieval Tool (IRT), which implements the reu se. The ADT sub-component enhances the quality of software development permitting a correct analysis, and design and a satisfactory document ation. The IRT Tool is dedicated to reuse by retrieving parts of exist ing applications (retrieve) and by qualifying elements just created or updated (insertion). A faceted system adapted to the medical domain a llows an efficient search among the object database. Both tools contri bute to reducing the cost of software development. This paper presents the design and the implementation of these tools in the HELIOS framew ork.
