Extracting objects of Ada programs using module features
Yuming Zhou, Baowen Xu · 1999
Reengineering legacy systems written in conventional procedural languages to equivalent OO systems makes software more maintainable and reliable. In this paper a method for extracting objects from legacy Ada 83 systems using module features is proposed. First, we develop metrics to measure module cohesion. Then, effects on cohesion from changing module components are discussed and rules on how to extract inheritance relations among objects are given. Finally, an object identification tool in APAUS is described.
