Diverse development web methodologies currently exist in the field of Model-Driven Web Engineering (MDWE), each of which covers different Levels of Abstraction on Model-Driven Architecture (MDA): Computation Independent Model (CIM), Platform Independent Model (PIM), Platform Specific Model (PSM), and Code. Given the high number of methodologies available, it has become necessary to define objective evaluation tools to enable development teams to improve their methodological environment and help designers of web methodologies design new effective and efficient tools, processes and techniques. Since proposals are constantly evolving, the need may arise not only to evaluate the quality but also to find out how it can be improved. This paper presents an approach named QuEF (Quality Evaluation Framework) oriented towards evaluating, through objectives measures, the quality of information technology infrastructure, mainly in MDWE methodology environments.

To manage the development of cooperative information systems that support the dynamics and mobility of modern businesses, separation of concern mechanisms and abstractions are needed. Model driven development (MDD) approaches utilize abstraction and transformation to handle complexity. In MDD, specifying transformations between models at various levels of abstraction can be a complex task. Specifying transformations for pervasive system services that are tangled with other system services is particularly difficult because the elements to be transformed are distributed across a model. This paper presents an aspect oriented model driven framework (AOMDF) that facilitates separation of pervasive services and supports their transformation across different levels of abstraction. The framework facilitates composition of pervasive services with enterprise services at various levels of abstraction. The framework is illustrated using an example in which a platform independent model of a banking service is transformed to a platform specific model.

Over the last few years, as they evolve with business needs and technology, enterprises are faced with the need to adapt their business processes to work in open settings. In such settings, the automation and the interoperability of business process and applications become a key concern. The Model Driven Architecture (MDA) is introduced as an approach to cope with this challenge. MDA specifies four levels of abstraction, most of the existing studies focus on modeling and transforming the Platform-Independent Model (PIM) to Platform-Specific Model (PSM) levels, while the more conceptual level, the Computation-Independent Model (CIM) is often presumed as present and is not further studied. In this paper, we propose an approach for transforming a CIM into a PIM using the core modeling concepts of the Unified Modeling Language (UML). One important characteristic of this approach is that it provides a method to capture and describe the requirements of the business process using a use cases model. The other important characteristic is proposing an architecture of the PIM based on the classes model. The execution of the transformation is programmed by the Query View Transformation (QVT) language.

The paper proposes a new data object-driven approach to data quality evaluation. It consists of three main components: (1) a data object, (2) data quality requirements, and (3) data quality evaluation process. As data quality is of relative nature, the data object and quality requirements are (a) use-case dependent and (b) defined by the user in accordance with his needs. All three components of the presented data quality model are described using graphical Domain Specific Languages (DSLs). In accordance with Model-Driven Architecture (MDA), the data quality model is built in two steps: (1) creating a platform-independent model (PIM), and (2) converting the created PIM into a platform-specific model (PSM). The PIM comprises informal specifications of data quality. The PSM describes the implementation of a data quality model, thus making it executable, enabling data object scanning and detecting data quality defects and anomalies. The proposed approach was applied to open data sets, analysing their quality. At least 3 advantages were highlighted: (1) a graphical data quality model allows the definition of data quality by non-IT and non-data quality experts as the presented diagrams are easy to read, create and modify, (2) the data quality model allows an analysis of "third-party" data without deeper knowledge on how the data were accrued and processed, (3) the quality of the data can be described at least at two levels of abstraction - informally using natural language or formally by including executable artefacts such as SQL statements.

The Model-Driven Architecture approach to software development uses transformation models for transforming Platform-Independent Models (PIM) into Platform-Specific Models (PSM) as its core software development strategy. The Model-Driven Architecture (MDA) approach and corresponding standards of the software development based on models have been initiated by the Object Management Group. In this chapter, the authors analyze the basic models of MDA (i.e., Computational Independent Model [CIM], PIM, and PSM) using a suitable example and formalize the model transformations for transforming PIM into PSM. These transformations have been illustrated through the generation of a Relational Model, an Enterprise Java Bean (EJB) Model, and a Web Model from PIM for the example under consideration, using UML profile, and keeping in mind the property of reusability of models in MDA transformations. The focus has been on the specification and formalization of rules needed to get the Relational PSM, EJB PSM, and Web PSM from PIM. A transformation tool, whose functionality of transformation of PIM into Relational PSM, EJB PSM, and Web PSM, is illustrated in this chapter.

The model-driven architecture (MDA) is an approach to model-centric software development. The concepts of models, metamodels, and model transformations are at the core of MDA. Model-driven development (MDD) distinguishes different kinds of models: the computation-independent model (CIM), the platform-independent model (PIM), and the platform-specific model (PSM). Model transformation is the process of converting one model into another model of the same system, preserving some kind of equivalence relation between them. One of the key concepts behind MDD is that models generated during software developments are represented using common metamodeling techniques. In this chapter, we analyze an integration of MDA metamodeling techniques with knowledge developed by the community of formal methods. We describe a rigorous framework that comprises the NEREUS metamodeling notation (open to many other formal languages), a system of transformation rules to bridge the gap between UML/OCL and NEREUS, the definition of MDA-based reusable components, and model/metamodeling transformations. In particular, we show how to integrate NEREUS with algebraic languages using the Common Algebraic Specification Language (CASL). NEREUS focuses on interoperability of formal languages in MDD.

Model-driven architecture (MDA) is an alternative approach of software engineering that allows an automatic transformation from business process model to code model. In MDA there are two transformation kinds: transformation from computing independent model (CIM) to platform independent model (PIM) and transformation from PIM to platform specific model (PSM). In this chapter, the authors based on CIM to PIM transformation. This transformation is done by developing a platform that generates class diagram, presented in XMI file, from specifications that are presented in user stories, which are written in natural language (English). They used a natural language processing (NLP) tool named “Stanford Core NLP” for extracting of the object-oriented design elements. The approach was validated by focusing on two case studies: firstly, comparing the results with the results other researchers; and secondly, comparing the results with the results obtained manually. The benefits of the approach are aligned with agile methods goals.
