Evolution Framework for Software Architecture Using Graph Transformation Approach

This paper presents a graph transformation approach to software architecture evolution. Evolution is inevitable over the course of the complete life of complex software intensive systems and more importantly of entire product families. However, not only instance models, but also type models and entire modelling languages are subject to change. Obviously software architecture is the centerpiece of software systems and acts as reference point for many development activities, and few of today's software systems are built to accommodate evolution. Evolution is primarily reflected in and facilitated through the software architecture. In this paper we focus on the different dimensions of architecture evolution with an automated evolution process of software architecture using graph transformation. The rules for the potential architecture evolutions operators are defined using AToM graph transformation tool.
