Use Case Realization in Software Reverse Engineering

Abstract

The Use Case Diagram (UCD) is a visual form of system design that helps software developers comprehend the system behavior. Maintaining and updating the system can be a difficult task when it has no visualization of a system behavior or software requirement specification document. Reverse engineering is an approach used to extract software requirement specifications from the existing systems. Research in reverse engineering has shown various techniques in which the processes are not fully understood. This study analyzes the University Community Services Information System (UCSIS) as the existing system in three processes: identifying the system domain process, elaborating system features by implementing the event table, and constructing the use case realization. The results showed that a UCD could be generated through the reverse engineering process on the existing system. Furthermore, a new feature for system improvement can also be detected using this method. It is expected that the reverse engineering approach in this study can be used as guidance for the software development team in extracting the use case diagram from the existing systems.
