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.","PeriodicalId":44125,"journal":{"name":"Journal of Object Technology","volume":"1 1","pages":"35-36"},"PeriodicalIF":0.8,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47005247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":44125,"journal":{"name":"Journal of Object Technology","volume":"1 1","pages":"101-103"},"PeriodicalIF":0.8,"publicationDate":"2019-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49445055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":44125,"journal":{"name":"Journal of Object Technology","volume":"54 1","pages":"21-27"},"PeriodicalIF":0.8,"publicationDate":"2007-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90759086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":44125,"journal":{"name":"Journal of Object Technology","volume":"51 1","pages":"44-51"},"PeriodicalIF":0.8,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86007176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
