    A Practical Example for Model-Driven Web Requirements

    The number of approaches for Web environments has grown very fast in the last years: HDM, OOHDM, and WSDM were among the first, and now a large number can be found in the literature. With the definition of MDA (Model- Driven Architecture) and the acceptance of MDE (Model-Driven Engineering) techniques in this environment, some groups are working in the use of metamodels and transformations to make their approaches more powerful. UWE (UMLBased Web Engineering) or OOWS (Object-Oriented Web Solutions) are only some examples. However, there are few real experiences with Web Engineering in the enterprise environment, and very few real applications of metamodels and MDE techniques. In this chapter the practical experience of a Web Engineering approach, NDT, in a big project developed in Andalusia is presented. Besides, it shows the usability of metamodels in real environments

    Metamodeling or profiling: a practical case in the web engineering domain

    Get PDF
    Model Driven Development (MDD) provides several choices for the definition of modeling languages. The definition of a complete metamodel and the customization of a given metamodel using profiles are common approaches. In our opinion neither of these approaches is better than the other, and the choice should depend on the characteristics of each project. This paper describes our experiences defining a graphical notation for the characterization of web navigational maps based on a MOF metamodel and a UML profile. The advantages and drawbacks of both approaches are examined, as well as the solution selected for our project.Presentado en el VIII Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informática (RedUNCI

    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

    Using Web services choreography to support an extensible and flexible system development process

    Systems Engineering (SE) controls a complex environment consisting of various collaborative subsystems. Each subsystem demands different kind of requirements and follows a specific strategy for its development process. Unifying and harmonizing the development process of all collaborative subsystems towards achieving the ultimate integrated system is one of the main challenges of SE. This work introduces a new approach towards having a generic SE unified process applicable to various environments. We suggest a service-oriented framework for SE process implemented using Web Services, and describe the process scenario in a machine-friendly abstract layer over the Development Process. This description layer choreographs collaborative subsystems and is implemented by a Web Services Choreography Description Language (WSCDL). It also covers Interface Management concerns of SE. In such an environment, as long as all services follow a unique framework for the SE process such as the one specified by the International Council on Systems Engineering (INCOSE), each phase of the process would then be an anonymous service implemented by a different vendor. As the result, an organization could easily customize its own specific development environment by editing this choreography layer according to its specific development policies, and then tailor its own desired development environment by choosing and integrating various services available on the Web.

    Using Web services choreography to model business process in e-commerce

    Web modeling languages like WebML (Web modeling Language), OOHDM (Object Oriented Hypermedia design) are evolved from hypermedia models. And they pay attention only to hypermedia modeling and model business rules as a form of navigation, this is called business process emulation. Our approach is to use web service peer-peer language, such as WS-CDL to model business process in an e-commerce application. In this way we introduce a new layer that models all the business rules using WS-CDL In this approach the hypermedia model models only navigation using WebML and once business process is initiated from simple navigation the process layer defined using WS-CDL will execute the business rules. By constructing a case study to test this hybrid-modeling framework, we hypothesise that this newly released peer-peer collaborative language for web-services can be used to model the concepts of business process. Thus we get a unique approach to model business process along with navigation. This approach is a proposed solution to the issues of business process emulation.

    Automated Functional Testing based on the Navigation of Web Applications

    Web applications are becoming more and more complex. Testing such applications is an intricate hard and time-consuming activity. Therefore, testing is often poorly performed or skipped by practitioners. Test automation can help to avoid this situation. Hence, this paper presents a novel approach to perform automated software testing for web applications based on its navigation. On the one hand, web navigation is the process of traversing a web application using a browser. On the other hand, functional requirements are actions that an application must do. Therefore, the evaluation of the correct navigation of web applications results in the assessment of the specified functional requirements. The proposed method to perform the automation is done in four levels: test case generation, test data derivation, test case execution, and test case reporting. This method is driven by three kinds of inputs: i) UML models; ii) Selenium scripts; iii) XML files. We have implemented our approach in an open-source testing framework named Automatic Testing Platform. The validation of this work has been carried out by means of a case study, in which the target is a real invoice management system developed using a model-driven approach.Comment: In Proceedings WWV 2011, arXiv:1108.208

    An Analysis of Model-Driven Web Engineering Methodologies

    Get PDF
    In the late 1990’s there was substantial activity within the “Web engineering” research community and a multitude of new Web approaches were proposed. However, numerous studies have revealed major gaps in these approaches, including coverage and interoperability. In order to address these gaps, the Model-Driven Engineering (MDE) paradigm offers a new approach which has been demonstrated to achieve good results within applied research environments. This paper presents an analysis of a selection of Web development methodologies that are using the MDE paradigm in their development process and assesses whether MDE can provide an effective solution to address the aforementioned problems. This paper presents a critical review of previous studies of classical Web methodologies and makes a case for the potential of the MDWE paradigm as a means of addressing long-standing problems of Web development, for both research and enterprise. A selection of the main MDWE development approaches are analyzed and compared in accordance with criteria derived from the literature. The paper concludes that this new trend opens an interesting new way to develop Web systems within practical projects and argues that some classical gaps can be improved with MDWE.Ministerio de Educación y Ciencia TIN2010-12312-EJunta de Andalucía TIC-578

    [EN] This study presents MoWebA, a navigational role-centric model driven development (MDD) proposal for web applications development. The approach was conceived considering a previous study of web methods and analysing some open issues. This article presents the fundamentals of the proposal; the methodological aspects for modelling and transformation processes; and the defined notations/techniques for modelling and transformation tasks, including their abstract and concrete syntax definitions. We include a summary of the validation experiences and main results, and a comparison against other related proposals, in order to highlight the main contributions of MoWebA.This research is partially supported by the CONACYT (Paraguay), through the INV-056 Project.González Toñánez, M.; Cernuzzi, L.; Pastor López, O.
