The process of cloning variants of a system to accommodate increasing customization is often state of the practice where code duplication is caused by the combination of maintenance problems, high customization, and time pressure. This particular situation motivates the research on similarity analysis of system variants. ...

Die Nutzung von Cloud-Architekturen – ob nun unternehmensintern („private cloud“) oder zunehmend auch bei entsprechenden Service- Unternehmen („public cloud“) – wird immer mehr zu einer gängigen Methode, IT-Leistungen zu virtualisieren und bei externen Anbietern zu betreiben. Neben den technischen und fachlichen Aspekten ...

In our research, we investigate design processes of future software systems. Our vision is that software services are provided in a world-wide distributed market and are composed automatically in order to fulfil individual user requests on-the- fly. This On-The-Fly Computing (OTF) software provision can be defined and ...

In diesem Artikel beschreiben wir, wie wir in zwei Projekten mit Hilfe von domänenspezifischen Edito- ren evolutiona ̈r die Art und Weise verbessert haben, wie versicherungsmathematische Berechnungen umgesetzt werden. Im einen Fall wurde eine bestehende, schwer lesbare textuelle Syntax ersetzt durch eine an mathematische ...

Test case reuse in migration projects brings double benefit: reuse of valuable knowledge as well as time and cost savings. Due to system changes, a direct reuse of test cases might be impossible. To facilitate reuse, the migration context, from both system migra- tion as well as testing perspective, has to be consid- ...

Research data management is of the utmost importance in a world where research data is created with an ever increasing amount and rate and with a high variety across all scientific disciplines. This paper especially discusses software engineering challenges stemming from creating a long-living software system. It aims ...

Information systems are subject to continuous change. In order to conduct empirical research on methods for software evolution, CoCoME was developed as a community-driven case study system. It is, however, not suitable for the validation of security-related approaches, as neither security nor privacy have been addressed ...

In this paper we report experiences made in the mostly finished process of modernization of the Bauhaus toolchain. We discuss the replacement of a hard-to-change intermediate representation that is only accessible in Ada by a modern one that is both language-independent and easy-to-change. Furthermore, we describe how ...
