An Object Structure Extraction Technique for Object Reusability Improvement Based on Legacy System Interface.

This paper suggests a technique, OSET(An Object Structure Extraction Technique for Object Reusability Improvement Based on Legacy System Interface) for reuse and reengineering by analyzing the Legacy System interface to distill the meaningful information from them and disassemble them into object units which are to be integrated into the next generation of systems. The OSET method consists of a procedure with 4 steps: 1) the interface use case analysis step, 2) the interface object dividing step, 3) the object structure modeling step, and 4) the object model integration step. In step 1, the interface structure and information about the interaction between the user and the Legacy System are obtained. In step 2, the interface information is divided into semantic fields. In step 3, the structural and collaborative relationship is studied and modeled among interface objects. Finally, in step 4, the object model integration step, integrates the models and improves the integrated model at a higher level. [ABSTRACT FROM AUTHOR]
