Design patterns detection based on its domain

Software maintenance is an important issue during the software design life cycle, especially, in late stages. Frequent changes in the software system with lack of documentation lead to the increase in the cost of maintenance. For this reason an important step for software maintenance is detecting patterns from the source code to provide relevant information that can help in understanding the system design and improve its documentation. Design patterns help maintainers and developers to understand the implementation of any software system which make software maintenance process faster and well-informed. Also it decreases the time and efforts that are needed in learning the software. Detecting patterns is not an easy task because the nature of design patterns. This research introduces a detection process based on software domains. This work is done through collecting five different domains for Java open source code. The dynamic analysis approach is used in extracting patterns. The experimental results showed that there are existing some common patterns between source codes which have the same domain in some source codes.
