An approach for Model-Driven test generation

The test phase is one of the most important phases in software development. However, in practice, little research has been carried out in this field. Model-Driven Engineering is a new paradigm that can help to minimize test cases generation costs and can ensure quality of results. This paper presents the application of the MDE paradigm in the systematic, even automatic, generation of System Test Software.Ministerio de Educación y Ciencia TIN2007-67843-C06 03Ministerio de Educación y Ciencia TIN2007-30391-

Two Hemisphere Model Driven Approach for Generation of UML Class Diagram in the Context of MDA

The Model Driven Architecture (MDA) separates the system business aspects from the system implementation aspects on a specific technology platform. MDA proposes a software development process in which the key notions are models and model transformation, where the input models are platform independent and the output models are platform specific and can be transformed into a format that is executable. In this paper principles of MDA and model transformations are applied for generation of UML class diagram from two hemisphere model, which is presented in the form of business process model related with concept model. Two hemisphere model is developed for the problem domain concerned with an application for driving school and UML class diagram is generated using the approach offered in the paper

An affinity analysis based CIM-to-PIM transformation

To tackle the problems such as the imperfection and inconsistency in software requirements in traditional Computation Independent Model (CIM) modelling, the low degree of automation as well as the imperfection in the description of Platform Independent Model (PIM) in CIM-to-PIM transforming, in this article, we propose a Business-Process-based CIM modelling method and a CIM-to-PIM transformation approach. Business Process Model is used to express CIM, and UML‘s Sequence Diagram, State Chart Diagram as well as Class Diagram are used to express PIM. Firstly, the users’ requirements are obtained through business process models. We extract use cases from business processes and create use case specifications. A verification mechanism is also added for the use case specification. Secondly, we transform CIMs into PIMs automatically with use case specifications as the inputs as well as combining with use case based thinking, responsibility based thinking and affinity analysis. Finally, by comparing with the methods in other studies, we conclude that methods proposed in this article can ensure model integrity and increase the degree of model transformation automation

Towards a Subject-Oriented Model-Driven Framework

AbstractModel-Driven Architecture is an approach which tackles such problems as: the high availability that a software product requires to be ready for use, the high degree of evolution that a software system has nowadays, etc. However, in the development of large complex systems, the benefits of that approach have been diminished due to the size and complexity of models that describe these kinds of systems. At this point Aspect-Oriented Software Development (AOSD) appears to improve the understanding, reusability and adaptation of the software artefacts. Its mechanism is based on modularization of crosscutting concerns in well-identified isolated entities called aspects. For this reason we propose to use together AOSD and MDA in the hope of reducing the shortcomings of the latter. Thus, aspects like security, replication, real-time constraints, etc., will be modelled by specialist modellers independently throughout the MDA framework. Our proposal exploits a tool for checking the consistency between different models (aspects) at the same level of abstraction; supporting the traceability of UML elements, requirements, and concerns; and controlling the impact of changes throughout the MDA framework

A Framework for Evaluating Model-Driven Self-adaptive Software Systems

In the last few years, Model Driven Development (MDD), Component-based Software Development (CBSD), and context-oriented software have become interesting alternatives for the design and construction of self-adaptive software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the modularity, flexibility, adaptability, and reliability of software systems. An analysis of these technologies shows them all to include the principle of the separation of concerns, and their further integration is a key factor to obtaining high-quality and self-adaptable software systems. Each technology identifies different concerns and deals with them separately in order to specify the design of the self-adaptive applications, and, at the same time, support software with adaptability and context-awareness. This research studies the development methodologies that employ the principles of model-driven development in building self-adaptive software systems. To this aim, this article proposes an evaluation framework for analysing and evaluating the features of model-driven approaches and their ability to support software with self-adaptability and dependability in highly dynamic contextual environment. Such evaluation framework can facilitate the software developers on selecting a development methodology that suits their software requirements and reduces the development effort of building self-adaptive software systems. This study highlights the major drawbacks of the propped model-driven approaches in the related works, and emphasise on considering the volatile aspects of self-adaptive software in the analysis, design and implementation phases of the development methodologies. In addition, we argue that the development methodologies should leave the selection of modelling languages and modelling tools to the software developers.Comment: model-driven architecture, COP, AOP, component composition, self-adaptive application, context oriented software developmen

Transformation From CIM to PIM: A Systematic Mapping

Model Driven Architecture (MDA) is the most prominent and accepted methodology based on the Model Driven Development (MDD) principles. MDA includes three abstraction levels: Computer Independent Models (CIM), Platform Independent models (PIM) and Platform speci c models (PSM). MDA encourages the automatic transformation of models as a means to increase the speed of the software development process and to prevent human errors. There are plenty of solutions to transform PIMs to PSMs, however the CIM to PIM transformation does not receive a similar attention. In that sense, this paper aims to describe a systematic mapping to analyze the main characteristics of the approaches that deal with the CIM to PIM transformation as well as to discuss research directions stemming out from our analysis. The results of this mapping study could be a valuable information source for the scienti c community in order to know the real advances in this topic and to avoid unnecessary effort dealing with problems that have already been addressed. For example, this study yielded the models at the CIM level that have already been transformed into models at the PIM level. Hence, with this information, the researchers could focus their attention on nding solutions to transform those models at CIM level that have not been transformed into models at PIM level. Likewise, this mapping study provides information regarding the technological support of this type of transformation. This information could be useful for those software projects interested to adopt MDA.Postdoctoral Fellowship through the Institute of Computer Technologies and Information Security, Southern Federal University PD/20-02-K

Measuring the Quality of Model-Driven Projects with NDT-Quality

Model-driven web engineering (MDWE) is a new paradigm which provides satisfactory results in the development of web software systems. However, as can be concluded from several research works, MDWE provokes traceability problems and the necessity of managing constraints in metamodel instances and transformation executions. The management of these aspects is usually executed manually in the most of MDWE approaches. Nevertheless, model-driven paradigm itself can offer suitable ways to manage them. This chapter presents NDT-Quality, an approach to measure the quality of web projects developed with NDT (navigational development techniques), and offers a view about the application of this tool in real web projects.Ministerio de Educación y Ciencia TIN2007-67843-C06-03Ministerio de Educación y Ciencia TIN2007-30391-

MDA-based interoperability establishment using language independent information models

Nowadays, more and more enterprises realize that one important step to success in their business is to create new and innovative products. Many times the solution to do that is to abandon the idea of an enterprise as an "isolated island", and get collaboration with others: worldwide non-hierarchical networks are characterized by collaboration and non-centralized decision making. This paper proposes a conceptual model common to the entire business network, in a framework that enables the abstraction of individual models at their meta-level and increase language independency and interoperability, keeping all the enterprise software's integrity intact. The strategy presented allows an incremental mapping construction, to achieve growing integration.publishersversionpublishe
