Title: Leveraging Configuration Management and Product Evolution of SPL Using Variability Aware Design Patterns
Author Name:K.L.S. Soujanya, and A. Ananda Rao
Synopsis:
Software Product Line (SPL) is an emerging approach to satisfy the ever-increasing customization demands by reusing commonalities and variability's. Variability - aware design patterns can leverage SPL configuration management and evolution of new products. Design pattern is a blueprint or model solution to a frequently occurring design problem. Variability aware design patterns can address variability and help in customizing software products. Modularization of artefacts and reusability of them can be realized by using design patterns. Design patterns in SPL is relatively used in new research area. However, composite design patterns that are variability-aware can lead to the realization of high quality SPL. In this context, the configuration management and product derivation are to be conceived and handled. There are no dedicated efforts found in the literature to leverage the usage of design patterns in SPL. The authors proposed a framework and provided provision for variability-aware design patterns. They use the concept of roles and map them to variability model. Then they map design pattern roles to artefacts thus realizing variability with industry best practices. This will help in improving the dynamic reconfiguration of SPL artefacts. Their empirical evaluation shows that the approach improved performance up to 20% with respect to configuration management of SPL and product derivation. The prototype demonstrates the proof of concept.
