Variability management in database applications
Mathieu Humblet, Dang Vinh Tran, Jens H. Weber, Anthony Cleve · 2016
Complex software products are often subject to application context specific configuration and variations. Variability management is a critical aspect of engineering software product families efficiently. However, the variability management on the data aspect of systems has received less attention. In this paper, we present SVL Tool, a plug-in for the Case Tool DB-Main which enables software engineers to model feature models, map them to database schema elements, and finally produce a new database schema including only the selected features. We present the Simple Variability Language, a language designed on the basis of the Common Variability Language. We also present our results of applying SVL Tool to a case study, an Electronic Medical Records software program widely used in Canadian primary health care.
