1 Overview There are a number of techniques for analyzing and improving the performance of programs written in a general-purpose language. For model transformation languages such techniques are still unknown. These are domain-speci c languages, which, simply said, are used to update models or create new models. Thus, these languages realize important operations in the context of Model-Driven Development. Current research about the performance of transformations is strongly focused on the transformation engine, which executes the transformations. Consequently, we conducted an online survey to examine whether techniques for analyzing and improving the performance of transformations are needed. Overall, our data set consists the results of the online survey and the information necessary to repeat the survey. The questionnaire was fully answered by 84 participants.

Search-Based Software Engineering (SBSE) is about solving software development problems by formulating them as optimization problems. In the last years, combining SBSE and Model-Driven Engineering (MDE), where models and model transformations are treated as key artifacts in the development of complex systems, has become increasingly popular. While search-based techniques have often successfully been applied to tackle MDE problems, a recent line of research investigates how a model-driven design can make optimization more easily accessible to a wider audience. In previous model-driven optimization efforts, a major design decision concerns the way in which solutions are encoded. Two main options have been explored: a model-based encoding representing candidate solutions as models, and a rule-based encoding representing them as sequences of transformation rule applications. While both encodings have been applied to different use cases, no study has yet compared them systematically. To close this gap, we evaluate both approaches on a common set of optimization problems, investigating their impact on the optimization performance. Additionally, we discuss their differences, strengths, and weaknesses laying the foundation for a knowledgeable choice of the right encoding for the right problem.

Model transformations are at the heart of Model-Driven Software Development (MDSD) and, once composed in transformation chains to MDSD processes, allow for the development of complex systems and their automated derivation. While there already exist various approaches to specify and execute such MDSD processes, only few of them draw focus on ensuring the validity of the transformation chains, and thus, safe composition of transformations. In this paper, we present the TraCo composition system, which overcomes these limitations and evaluate and discuss the approach based on two case studies.

Late binding and subtyping create run-time overhead for object-oriented languages, especially in the context of both multiple inheritance and dynamic loading, for instance for Java interfaces. It is, however, generally agreed that the efficiency of Java and .Net systems comes from the fact that, in these languages, classes are in single inheritance. In this paper, we present the abstract architecture of a virtual machine for unrestricted multiple-inheritance, which should provide the same runtime efficiency as Java and .Net.

Aspect-oriented programming (AOP) has become a mature technology. Increasingly, calls for support of AOP on the software model level are being voiced. This paper addresses these calls by offering a meta-model of AspectJ in UML. Using the UML extension mechanisms, this meta-model is at the same time a profile to support AspectJ modelling in UML. In contrast to previous work, this profile offers complete meta-level integration of all AspectJ concepts. The use of standard XMI based modelling allows the use of the profile in commercially available CASE tools and supports easy code generation.

In this paper, we continue a series of papers that discuss specific design metrics [Alkadi 1999] [Alkadi 2000] [Alkadi 2001] [Alkadi 1998]. The design metric discussed in this paper is the Depth of Inheritance [DIT] metric. Design evaluation is a recurring step that should be performed and checked multiple times before committing to the final design implementation. Metrics are utilized to evaluate inheritance and reuse in order to take into account the greater number of abstraction levels inherent in object-oriented systems. Furthermore, they facilitate the designers to address cost estimation and product quality across all life-cycle stages of developing the final product.
