A graph of change impact analysis for distributed object-oriented software

Applying the change impact analysis to the distributed environment is not straightforward since it is based on the centralized system environment. In this paper, we investigate the change impact analysis of object-oriented software in the distributed environment. First, we categorize the types of change elements in object-oriented software into three disjoint sets: data, method, and class level changes. We then analyze the impact of each set of changes and represent it in the form of a distributed program dependency graph (DPDG). The DPDG is a graph showing the relationship of object oriented software-with data elements, classes, design documents, servers-and its minimized firewall in the distributed environment. Thus, the DPDG reduce the effort and element of software to re-test.
