Authentic descriptions of a software architecture are required as a reliable foundation for any but trivial changes to a system. Far too often, architecture descriptions of existing systems are out of sync with the implementation. If they are, they must be reconstructed. There are many existing techniques for reconstructing individual architecture views,(More)
Static analysis aims at recovering the structure of a software system, while dynamic analysis focuses on its run time behaviour. We propose a technique for combining the analysis of static and dynamic architectural information to support the task of architecture reconstruction. The approach emphasises the correct choice of architecturally significant(More)
Maintenance and evolution of complex software systems (such as mobile telephones) involves activities such as reverse engineering (RE) and software visualization. Although several RE tools exist, we found their architecture hard to adapt to the domain and problem specific requirements posed by our current practice in Nokia. In this paper, we present an open(More)
This paper proposes a UML-based software maintenance process. The process is guided by architectural descriptions and existing architectural models. The descriptions are given as variants of UML profiles describing the styles and rules relevant for a particular application domain. A reverse engineering subprocess, combining top-down and bottom-up reverse(More)
We present the work of establishing an integrated environment that facilitates architecture design, reconstruction, and maintenance in the entire life cycle of a software product line. This architecting environment (ART environment) has been used in modeling and analysis of both the designed platform architecture model and the reverse-engineered product(More)
The data regarding the components of a software system consists of a large amount of information such as version history, number of lines, defect density, and complexity measures. The ability to quickly grasp a comprehensive view of the evolution and dependencies of such information is the key to making informed decisions about future developments of the(More)
