객체 지향 CASE 도구에 대한 재구조화 실험 = An Experimant in Refactoring an Object-Oriented CASE Tool

다국어 초록 (Multilingual Abstract)

Object-oriented programming is often touted as promoting software reuse. However, it is recognized that objected-oriented software often need to be restructured before it can be reused. Refactroing is the process that changes the software structure to make it more reusable, easier to maintain and easier to be enhanced with new functionalities. This paper describes experience gained and lessons learned from restructuring OODesigner, a Computer Aided Software Engineering(CASE) tool that supports Object Modeling Technique(OMT). This tool supports a wide range of features such as constructing object modeler of OMT, managing information repository, documenting class resources, automatically generating C and Java code, reverse engineering of C and Java code, searching and reusing classes in the corresponding repository and collecting metrics data. Although the version 1.x was developed using OMT(i.e. the tool has been designed using OMT) and C , we recognized that the potential maintenance problem originated from the ill-designed class architecture. Thus this version was totally restructured, resulting in a new version that is easier to maintain than the ole version. In this paper, we briefly describe its restructuring process, emphasizing the fact that the Refactoring of the tool is conducted using the tool itself. Then we discuss lessons from these processes and we exhibit some comparative measurements of the developed version.
