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.

Sustainable Built Environments: Building Information Modeling, Biomaterials, and Regenerative Practices in Mexico

“…These obtained results, complemented by other research [73][74][75][76], suggest that it is a priority to address the following: (a) the establishment of new standards of characterization and change in the Unified System based on the performance of materials and biomaterials that ensure that the industry can benefit from a breakthrough with a high degree of replicability and confidence, as well as new tools to anticipate or simulate the long-term performance of these unique components; (b) the advanced and computer characterization of materials that require "machine-driven" data development and analysis, from the comparison of construction codes and standards with materials and biomaterials based on our own indicators for urban metabolism and the decarbonization of the city and buildings that allow for the realization of the digitalization of the development of materials to achieve the green transition, based on an integrated system to define the optimal, that is, cost, time, and resources; and (c) the model-based definition necessary for component design changes, which must be established on digital specifications that link the microstructure and evaluation of mechanisms, geometric characteristics, and the specific location of properties with manufacturing process routes for the optimization of process design for industrial applications aimed at balancing ecology and efficiency.…”

Enhancing Support For Senior Citizens: Development And Evaluation of The OSCA Information Management System With Agile Methodology and ISO/IEC 25010 Compliance

“…It is a visual form of system design that helps software developers comprehend the system's 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 (Andriyani et al, 2022). Figure 3 presents the Use Case Diagram of the system OSCA-IMSA.…”

Modelling Quality Assurance System Process Using UML Notation

“…In this paper adopted three UML diagrams which are use case diagram as a representative of system context and describes the system functional requirements, class diagram illustrates a system static's structure and the relationships between different objects and communication diagram. The Use Case Diagram (UCD) is a visual form of system design that helps software developers comprehend the system behavior [20]. List of actors are the stakeholders involved in AQA system represented in difference tables based on the AQA phases.…”
