    Using Aspect-orientation Techniques to Improve Reuse of Metamodels

    Metamodelling is an activity that attracts attention of the research community dealing with the Model- Driven Development (MDD). To be reusable in different MDD approaches a metamodel should be unaware of being extended by another metamodel. This property of metamodel is called obliviousness. This paper shows that current techniques implementing metamodels do not maintain obliviousness when some elements of the extended metamodel and the elements of the original model have association relations. Three different approaches to reuse of metamodels are analyzed. One of the approaches uses traditional object-oriented techniques. Two other approaches use aspect-oriented techniques. The paper shows that the third approach, which considers relationships as first-class citizens at the implementation level by using relationship aspects, guarantees obliviousness of metamodels.Ministerio de Ciencia y Tecnología TIC 2003-369

    Ontology-based patterns for the integration of business processes and enterprise application architectures

    Get PDF
    Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data. Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their applicability in business process-driven application integration is demonstrated

    Development of service-oriented architectures using model-driven development : a mapping study

    Get PDF
    Context: Model-Driven Development (MDD) and Service-Oriented Architecture (SOA) are two challenging research areas in software engineering. MDD is about improving software development whilst SOA is a service-based conceptual development style, therefore investigating the available proposals in the literature to use MDD when developing SOA may be insightful. However, no studies have been found with this purpose. Objective: This work aims at assessing the state of the art in MDD for SOA systems. It mainly focuses on: what are the characteristics of MDD approaches that support SOA; what types of SOA are supported; how do they handle non-functional requirements. Method: We conducted a mapping study following a rigorous protocol. We identified the representative set of venues that should be included in the study. We applied a search string over the set of selected venues. As result, 129 papers were selected and analysed (both frequency analysis and correlation analysis) with respect to the defined classification criteria derived from the research questions. Threats to validity were identified and mitigated whenever possible. Results: The analysis allows us to answer the research questions. We highlight: (1) predominance of papers from Europe and written by researchers only; (2) predominance of top-down transformation in software development activities; (3) inexistence of consolidated methods; (4) significant percentage of works without tool support; (5) SOA systems and service compositions more targeted than single services and SOA enterprise systems; (6) limited use of metamodels; (7) very limited use of NFRs; and (8) limited application in real cases. Conclusion: This mapping study does not just provide the state of the art in the topic, but also identifies several issues that deserve investigation in the future, for instance the need of methods for activities other than software development (e.g., migration) or the need of conducting more real case studies.Peer ReviewedPostprint (author's final draft

    Evaluation of the QVT Merge Language Proposal

    Get PDF
    -STF90 A05045This report has identified 29 weighted evaluation criteria representing desired properties of a model to model transformation language. These criteria have been used to evaluate the current QVT Merge specification. We have so far only been able to evaluate 21 of these criteria, mainly due to missing tool support. Some of the criteria are considered absolute in the sense that missing to fulfil such a criterion is considered a failure. The 21 evaluated criteria give a score of 59 out of a maximum possible score of 68 (language-based + example-based testing). We have also compared the QVT-Merge submission with the QVT-Compuware/Sun submission and at the time being the QVT-Merge seems to be the preferred one due to more support on the absolute criteria and better easy-to-use score. Eight transformation examples for solving six different transformation tasks have given a lot of insight on the ease of use criteria for both simple and complex transformations. When defining transformations using QVT Merge we believe that a lot of effort may be required in order to define the source and target  metamodels. The evaluation in this report could be improved by using the reference examples with alternative approaches published in the literature. An available QVT-Merge tool is necessary in order to provide evaluations of all the suggested criteria. In order to further investigate the usability of the graphical notation, we need to define more of the transformation examples graphically. Only one of the examples has been specified graphically in this version. The current evaluation has been done by a single evaluator who has only reviewed the transformation code that was written by somebody else. The evaluation will be further improved by incorporating input from other evaluators as well as evaluation from those who wrote the transformation code. Oppdragsgiver: EU Commissio

    Designing Traceability into Big Data Systems

    Full text link
    Providing an appropriate level of accessibility and traceability to data or process elements (so-called Items) in large volumes of data, often Cloud-resident, is an essential requirement in the Big Data era. Enterprise-wide data systems need to be designed from the outset to support usage of such Items across the spectrum of business use rather than from any specific application view. The design philosophy advocated in this paper is to drive the design process using a so-called description-driven approach which enriches models with meta-data and description and focuses the design process on Item re-use, thereby promoting traceability. Details are given of the description-driven design of big data systems at CERN, in health informatics and in business process management. Evidence is presented that the approach leads to design simplicity and consequent ease of management thanks to loose typing and the adoption of a unified approach to Item management and usage.Comment: 10 pages; 6 figures in Proceedings of the 5th Annual International Conference on ICT: Big Data, Cloud and Security (ICT-BDCS 2015), Singapore July 2015. arXiv admin note: text overlap with arXiv:1402.5764, arXiv:1402.575

    A Model-Driven Approach for Business Process Management

    Get PDF
    The Business Process Management is a common mechanism recommended by a high number of standards for the management of companies and organizations. In software companies this practice is every day more accepted and companies have to assume it, if they want to be competitive. However, the effective definition of these processes and mainly their maintenance and execution are not always easy tasks. This paper presents an approach based on the Model-Driven paradigm for Business Process Management in software companies. This solution offers a suitable mechanism that was implemented successfully in different companies with a tool case named NDTQ-Framework.Ministerio de Educación y Ciencia TIN2010-20057-C03-02Junta de Andalucía TIC-578

    Model driven product line engineering : core asset and process implications

    Get PDF
    Reuse is at the heart of major improvements in productivity and quality in Software Engineering. Both Model Driven Engineering (MDE) and Software Product Line Engineering (SPLE) are software development paradigms that promote reuse. Specifically, they promote systematic reuse and a departure from craftsmanship towards an industrialization of the software development process. MDE and SPLE have established their benefits separately. Their combination, here called Model Driven Product Line Engineering (MDPLE), gathers together the advantages of both. Nevertheless, this blending requires MDE to be recasted in SPLE terms. This has implications on both the core assets and the software development process. The challenges are twofold: (i) models become central core assets from which products are obtained and (ii) the software development process needs to cater for the changes that SPLE and MDE introduce. This dissertation proposes a solution to the first challenge following a feature oriented approach, with an emphasis on reuse and early detection of inconsistencies. The second part is dedicated to assembly processes, a clear example of the complexity MDPLE introduces in software development processes. This work advocates for a new discipline inside the general software development process, i.e., the Assembly Plan Management, which raises the abstraction level and increases reuse in such processes. Different case studies illustrate the presented ideas.This work was hosted by the University of the Basque Country (Faculty of Computer Sciences).

    Model transformations and Tool Integration

    Get PDF
    Model transformations are increasingly recognised as being of significant importance to many areas of software development and integration. Recent attention on model transformations has particularly focused on the OMGs Queries/Views/Transformations (QVT) Request for Proposals (RFP). In this paper I motivate the need for dedicated approaches to model transformations, particularly for the data involved in tool integration, outline the challenges involved, and then present a number of technologies and techniques which allow the construction of flexible, powerful and practical model transformations
