Web Quality

This chapter introduces the necessity to consider quality management activities as part of the Web engineering (WE) process to improve the final quality of Web applications with respect to creative practices. We explore principles and achievements that, uncovered in different Web quality lines of research, provide insights into how to deal with quality in each of the different workflows that a typical WE process defines, from requirements to implementation. Also, in order to preserve the semiautomatic nature of WE processes, we propose the definition of measurable concepts, measures, and decision criteria in a machine-readable way that facilitate the automation of the quality evaluation process, thus preserving the model-driven engineering (MDE) nature of WE processes. In this way, we are providing the user of a WE methodology with the advantages associated with managing quality from the early stages of development with little extra development costs.

Users consider usability aspects as a key factor when using Web applications. For this reason, in this work we take a special care in this very important issue. In particular, we are centred on usability aspects regarding business process driven Web applications. Therefore, in this work we gather a set of guidelines provided by experts in Web usability and present the solution designed in a particular Web engineering method that follows a model driven development approach. The provided solution bases on the introduction of these guidelines following two different approaches. The former implies handling usability guidelines at the modeling level. The latter implies using them for the definition of the transformation rules that generate the corresponding usable Web applications.

Many scholars have reported that the adoption of Model Driven Engineering (MDE) in the industry is still marginal. Real-life case studies, completed with convincing empirical data about the quality of the developed source code, is an effective way to persuade the industry that the adoption of MDE brings an actual added value. This paper reports about the assessment of the quality of the code outputted by xGenerator: a Java technology platform for the development of enterprise Web applications, which implements the MDE paradigm. Two recent papers from Aniche and his colleagues were selected to carry out the measurements. The former study is about metrics and thresholds for MVC Web applications, while the latter presents a catalog of six smells tailored to MVC Web applications. A big merit of both of these proposals is that they fix the metric thresholds by taking into account the MVC software architecture. The results of the empirical assessment, carried out on a real-life project, proved that the quality of the code is high.

Theoretical Foundations

Systems and applications aligned with new paradigms such as cloud computing and internet of the things are becoming more complex and interconnected, expanding the areas in which they are susceptible to attacks. Their security can be addressed by using model-driven engineering (MDE). In this context, specific IoT or cloud computing metamodels emerged to support the systematic development of software. In general, they are specified through semiformal metamodels in MOF style. This article shows the theoretical foundations of a method for automatically constructing secure metamodels in the context of realizations of MDE such as MDA. The formal metamodeling language Nereus and systems of transformation rules to bridge the gap between formal specifications and MOF are described. The main contribution of this article is the definition of a system of transformation rules called NEREUStoMOF for transforming automatically formal metamodeling specifications in Nereus to semiformal-MOF metamodels annotated in OCL.

The goal of this work is to facilitate the task of integrating measurement and redesign tools in modelling environments for Domain Specific Visual Languages (DSVLs), reducing or eliminating the necessity of coding. With this purpose, we have created a DSVL called SLAMMER that includes generalizations of some of the more used types of product metrics and frequent model manipulations, which can be easily customised for any other DSVL in a graphical way. The metric customisation process relies on visual patterns for the specification of the elements that should be measured in each metric type, while redesigns (as well as other actions) can be specified either personalizing generic templates or by means of graph transformation systems. The provided DSVL also allows creating new metrics, composing metrics, and executing actions guided by measurement values. The approach has been empirically validated by its implementation in a meta-modelling tool, which has been used for several DSVLs. In this way, together with the DSVL specification, a SLAMMER model can be provided containing a suite of metrics and actions that will become available in the final modelling environment. In this chapter we show a case study for a notation in the web engineering domain. As ensuring model quality is a key success factor in many computer science areas, even crucial in model-driven development, we believe that the results of this work benefit all of them by providing automatic support for the specification, generation and integration of measurement and redesign tools with modelling environments.

Adaptivity (the runtime adaptation to user profile data) and context-awareness (the runtime adaptation to generic context data) have been gaining momentum in the field of Web engineering over the last years, especially in response to the ever growing demand for highly personalized services and applications coming from end users. Developing context-aware and adaptive Web applications requires addressing a few design concerns that are proper of such kind of applications and independent of the chosen modeling paradigm or programming language. In this chapter we characterize the design of context-aware Web applications, the authors describe a conceptual, model-driven development approach, and they show how the peculiarities of context-awareness require augmenting the expressive power of conceptual models in order to be able to express adaptive application behaviors.

The consistent modeling of quality requirements for Web sites and applications at different stages of the life cycle is still a challenge to most Web engineering researchers and practitioners. In the present chapter, we propose an integrated approach to specify quality requirements to Web sites and applications. By extending the ISO 9126-1 quality views characteristics, we discuss how to model internal, external quality, and quality in use views taking into account not only the software features, but also the own characteristics of Web applications. Particularly, we thoroughly analyze the modeling of the content characteristic for evaluating the quality of information–so critical for the whole Web application eras. The resulting model represents a first step towards a multi-dimensional integrated approach to evaluate Web sites at different lifecycle stages.

As it will be clearer subsequently, two different technologies will be used for realizing the generation of the code; the first one predominantly focused on the generation of code for the Web applications that do not have an underlying business process, and that they do not require, therefore, the management of the relative problems. The second technology has been selected instead, to also keep in mind the business processes. In order to provide support to the designer in the design of the whole complex Web information system, it is essential to provide a suitable tool that hides the intrinsic complexity of the methodology supporting the designer in the application of the same that is often complex, and the tool has to be able to translate the design made up in a machine readable format to be able to use this design in the following automatic code generation of the Web application according to a model-driven approach. In this chapter, we introduce the design and implementation of the editor made up mainly of the architecture presented (and based on Eclipse™ Platform as illustrated in the preceding chapter) and on the methodological steps of integration among the several editors for the design and implementation of these guidelines.

The increasing complexity and the many different aspects that should be treated at the same time require flexible but powerful methodologies to support the development process. Every day, the requirements treatment in Web environments is becoming a more critical phase because developers need suitable methods to capture, define, and validate requirements. However, it is very important that these methods assure the quality of these requirements. The model-driven engineering is opening a new way to define methodological approaches that allow control and relate concepts that have to be treated. This chapter presents a Web methodological approach to deal with requirements, NDT (navigational development techniques) based on model-driven engineering. As it is presented, NDT proposes a set of procedures, techniques, and models to assure the quality of results in the Web requirements treatment.

Model-driven software engineering (MDE) has the basic assumption that the development of software systems from high-level abstractions along with the generation of low-level implementation code can improve the quality of the systems and at the same time reduce costs and improve time to market. This chapter provides an overview of MDE, state of the art approaches, standards, resources, and tools that support different aspects of model-driven software engineering: language development, modeling services, and real-time applications. The chapter concludes with a reflection over the main challenges faced by projects using the current MDE technologies, pointing out some promising directions for future developments.
