Case studies of optimized sequence diagram for program comprehension

In large project, source code becomes increasing complex and lengthy so program comprehension plays an important and significant role for developers. Sequence diagram generated using static source code or dynamic only approach provides limited execution coverage, additionally contains redundant, dead and fault driven methods, which increase the size of the diagram and complexity. In this paper, to address the problems, optimized sequence diagrams were developed by combining static source code and dynamic only approach, also incorporating various levels of abstraction in order to reduce complexity and provide complete behavior of the system. Case studies determined from the sequence diagram for three systems generated based on source code only and fully dynamic approach proved that the proposed optimized sequence diagrams were less complex and provided more detailed description of the functionality of the system.
