Item Open Access Interaction-based feature-driven model-transformations for generating E-forms(ACM, 2009-10) Tekinerdoǧan, Bedir; Aktekin, N.One of the basic pillars in Model-Driven Software Development (MDSD) is defined by model transformations and likewise several useful approaches have been proposed in this context. In parallel, domain modeling plays an essential role in MDSD to support the definition of concepts in the domain, and support the model transformation process. In this paper, we will discuss the results of an e-government project for the generation of e-forms from feature models. Very often existing model transformation practices seem to largely adopt a closed world assumption whereby the transformation definitions of models are defined beforehand and interaction with the user at run-time is largely omitted. Our study shows the need for a more interactive approach in model transformations in which e-forms are generated after interaction with the end-user. To show the case we illustrate three different approaches for generation in increasing complexity: (1) offline model transformation without interaction (2) model transformation with initial interaction (3) model-transformation with run-time interaction. Copyright©2009 ACM.Item Open Access Model-driven approach for supporting the mapping of parallel algorithms to parallel computing platforms(Springer, Berlin, Heidelberg, 2013) Arkin, E.; Tekinerdogan, Bedir; Imre, K.M.The trend from single processor to parallel computer architectures has increased the importance of parallel computing. To support parallel computing it is important to map parallel algorithms to a computing platform that consists of multiple parallel processing nodes. In general different alternative mappings can be defined that perform differently with respect to the quality requirements for power consumption, efficiency and memory usage. The mapping process can be carried out manually for platforms with a limited number of processing nodes. However, for exascale computing in which hundreds of thousands of processing nodes are applied, the mapping process soon becomes intractable. To assist the parallel computing engineer we provide a model-driven approach to analyze, model, and select feasible mappings. We describe the developed toolset that implements the corresponding approach together with the required metamodels and model transformations. We illustrate our approach for the well-known complete exchange algorithm in parallel computing. © 2013 Springer-Verlag.Item Open Access MoDSEL: model-driven software evolution language(IGI Global, 2013) Er, E.; Tekinerdogan, B.Model-Driven Software Development (MDSD) aims to support the development and evolution of software intensive systems using the basic concepts of model, metamodel, and model transformation. In parallel with the ongoing academic research, MDSD is more and more applied in industrial practices. Like conventional non-MDSD practices, MDSD systems are also subject to changing requirements and have to cope with evolution. In this chapter, the authors provide a scenario-based approach for documenting and analyzing the impact of changes that apply to model-driven development systems. To model the composition and evolution of an MDSD system, they developed the so-called Model-Driven Software Evolution Language (MoDSEL) which is based on a megamodel for MDSD. MoDSEL includes explicit language abstractions to specify both the model elements of an MDSD system and the evolution scenarios that might apply to model elements. Based on MoDSEL specifications, an impact analysis is performed to assess the impact of evolution scenarios and the sensitivity of model elements. A case study is provided to show different kind of evolution scenarios and the required adaptations to model elements. © 2014, IGI Global.
