A Practical Environment to Apply Model-Driven Web Engineering

The application of a model-driven paradigm in the development of Web Systems has yielded very good research results. Several research groups are defining metamodels, transformations, and tools which offer a suitable environment, known as model-driven Web engineering (MDWE). However, there are very few practical experiences in real Web system developments using real development teams. This chapter presents a practical environment of MDWE based on the use of NDT (navigational development techniques) and Java Web systems, and it provides a practical evaluation of its application within a real project: specialized Diraya.Ministerio de Educación y Ciencia TIN2007-67843-C06-03Ministerio de Educación y Ciencia TIN2007-30391-

An Analysis of Model-Driven Web Engineering Methodologies

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

A model-driven engineering approach for the uniquely identity reconciliation of heterogeneous data sources.

The objectives to be achieved with this Doctoral Thesis are: 1. Perform a study of the state of the art of the different existing solutions for the entity reconciliation of heterogeneous data sources, checking if they are being used in real environments. 2. Define and develop a Framework for designing the entity reconciliation models by a systematic way for the requirement, analysis and testing phases of a software methodology. For this purpose, this objective has been divided in three sub objectives: a. Define a set of activities, represented as a process which can be added to any software development methodology to carry out the activities related to the entity reconciliation in the requirement, analysis and testing phase of any software development life cycle. b. Define a metamodel that allows us to represent an abstract view of our model-based approach. c. Define a set of derivation mechanisms that allow to stablish the base for automate the testing of the solutions where the framework proposed in this doctoral thesis has been used. Considering that the process will be applied in the early stages of the development, it is possible to say that this proposal applies Early Testing. 3. Provide a support tool for the framework. The support tool will allow to a software engineer to define the analysis model of an entity reconciliation problem between different and heterogeneous data sources. The tool will be represented as a Domain Specific Language (DSL). 4. Evaluate the results obtained of the application of the proposal in a real-world case study
