A UML profile for delta-oriented programming to support software product line engineering

Abstract

Feature-based approaches to software design, like delta-oriented programming, are well-suited to support multi-product software development paradigms, such as Software Product Lines. Currently, the popular UML notation does not support delta-oriented software design, so that several ad-hoc notations tend to be used. This paper presents a systematic approach to import concepts from delta-oriented programming into the mainstream notation UML. This is done with minimal overhead by specifying a new, slim, delta-oriented UML profile. It is compatible with languages that support delta-oriented programming such as DeltaJ and ABS. The usefulness of the profile is evaluated with a case study.
