Dynamic Visualization of Java Software System Using Sequence Diagram

摘要

The object oriented programming language is complex and difficult to understand for a novice programmer, so program comprehension and visualization of source code using sequence diagram play a vital and significant role for programmers to understand the object oriented programming concepts. The sequence diagram generated through static source code or dynamic only approach contains large methods and objects which make the diagram bulky and also increases the complexity of the diagram. In this paper, to address these problems, optimized sequence diagram (OSD) were developed by combining static source code and dynamic execution trace information and also incorporating various levels of abstraction to reduce complexity and provide complete end to end behavior of the system. The case study is conducted using the banking system to provide quantitative analysis and determine the performance of the optimized sequence diagram approach. The statistical analysis is conducted based on the experimental result using OSD to prove that comprehension of the optimized sequence diagram is greater than the static and dynamic sequence diagram.
