Detecting dependencies in Enterprise JavaBeans with SQuAVisiT

We present recent extensions to SQuAVisiT, Software Quality Assessment and Visualization Toolset. While SQuAVisiT has been designed with traditional software and traditional caller-callee dependencies in mind, recent popularity of Enterprise JavaBeans (EJB) required extensions that enable analysis of additional forms of dependencies: EJB dependency injections, object-relational (persistence) mappings and Web service mappings. In this paper we discuss the implementation of these extensions in SQuAVisiT and the application of SQuAVisiT to an open-source software system. Keywords: Java, Visualization, Containers, Web services, Open source software, Computer architectur

Modular modeling with a computational twist in Metamod

Model-driven engineering (MDE) is a software development methodology that promises to alleviate the complex task of writing software. To achieve its goals, MDE makes use of models. Although models are concise representations of the knowledge in a domain, they can become large and complex. In dealing with complexity, modularity has proven to be a good ally for engineers in general software development. Inspired by this, we set to explore modularity for models. To this end, we incorporated two mechanisms: grouping and fragment abstractions. The second ingredient, in particular, gives rise to an interesting combination between modeling elements and computational elements. To test our ideas, we have implemented a prototype metamodeling language called MetaMod. To highlight MetaMod's essential features we have included a small example for train tracks.</p

Modular multilevel metamodeling with metaMod

The increase of software driven functionalities in products leads to more complex software. Helping with the construction of this complex software, models in model-driven engineering have become larger and more complex. As a consequence, the models are harder to understand and the need to reuse models is augmented. Given these two goals: increasing understandability and reuse of models, and inspired by modular programming in the realm of general software development and its role in fulfilling these goals (among others), we set to explore modularity mechanisms for models. Although work has been done to address the issue of modularity in models, there is no commonly agreed method for doing it. Ours is an attempt to discover the basic modularity elements for models. We have done this in the context of a simple multilevel metamodeling language that we designed, MetaMod, where we introduced a few modularity mechanisms: groups, fragment abstractions and applications. To test the feasibility of our ideas, we created a prototype of this language and a few exploratory examples in the language

Language workbench challenge 2016 Citation for published version (APA): Language Workbench Challenge 2016: the JetBrains Meta Programming System

Abstract This paper describes a solution for the SPLASH 2016 Language Workbench Challenge (LWC) workshop, using the JetBrains Meta Programming System (MPS) language workbench. As the main focus of the LWC is on implementation and not on writing a paper, we used the mbeddr documentation language to describe the solutions to the challenges posed in the LWC. In this way, the showcasing of a solution is co-located with its implementation, making it easier for the reader to try out the solutions and to better understand them. Therefore we would encourage you to actually open the solution implementation (see README.md for setting it up) and try it out. JetBrains MPS has evolved into a powerful and flexible tool that can be used to address most of the language engineering challenges in the LWC. The feature-richness, and the scale of practical applicability of Jetbrains MPS increases even more when using the mbeddr platform extensions and other plugins developed by the MPS community
