Metamodels Evaluation of Web Engineering Methodologies to Develop Web Applications

The purpose of a metamodel in web engineering methodologies is for the platform independent analysis as well as the design of the content, navigation, and presentation issues of web applications. In the previous years, numbers of methodologies for the development of web applications were proposed, and most of them defined their notation for creating metamodels. The increasing expansion and complexity of web applications are a new challenge for web software developers. This paper presents a comparison study between metamodel of the three methodologies which are; UML-Based Web Engineering (UWE), Web Modeling Language (WebML) and Object Oriented Hypermedia (OOH). The aim is to show the capability of the methodologies to address the challenges in developing the web applications. The evaluation results presented in this paper help the designer in providing initial knowledge of the strengths and weaknesses of the three methodologies for developing web applications.

A semantic web enabled approach to reuse functional requirements models in web engineering

Web engineering has emerged as a new software discipline to specifically address the challenges and complexities of developing high quality web applications. A main theme in different web engineering methodologies is to employ model driven development approaches. This increases the level of abstraction and formalism to the extent that machines can better involve in the development process and provide more automation, e.g. automatic code generation from the models. Despite their benefits, a main problem of these model-driven methodologies is that developing each new web application implies creating a probably large number of models from scratch. Hence, model reuse can be considered as the main solution to this problem. In this paper, a semantic web enabled approach is proposed for reusing models, specifically functional requirements models. It takes the brief description of the functional requirements of a new web application in terms of UML use case diagram, and semi-automatically generates the draft of the corresponding detailed description in terms of a set of UML activity diagrams. This is performed by utilizing a repository which contains semantic representation of the models of the previous web applications. The proposed approach is based on novel algorithms for annotating activity diagrams, measuring similarity of use cases, and adapting activity diagrams. The experimental evaluations demonstrate that the proposed approach is promising, and it has good precision and effectiveness.

Mockup-Driven Development: Providing agile support for Model-Driven Web Engineering

ContextAgile software development approaches are currently becoming the industry standard for Web Application development. On the other hand, Model-Driven Web Engineering (MDWE) methodologies are known to improve productivity when building this kind of applications. However, current MDWE methodologies tend to ignore important aspects of Web Applications development supported by agile processes, such as constant customer feedback or early design of user interfaces. ObjectiveIn this paper we analyze the difficulties of supporting agile features in MDWE methodologies. Then, we propose an approach that eases the incorporation of well-known agile practices to MDWE. MethodWe propose using User Interface prototypes (usually known as mockups) as a way to start the modeling process in the context of a mixed agile-MDWE process. To assist this process, we defined a lightweight metamodel that allows modeling features over mockups, interacting with end-users and generating MDWE models. Then, we conducted a statistical evaluation of both approaches (traditional vs. mockup-based modeling). ResultsFirst we comment on how agile features can be added to MDWE processes using mockups. Then, we show by means of a quantitative study that the proposed approach is faster, less error-prone and still as complete as traditional MDWE processes. ConclusionThe use of mockups to guide the MDWE process helps in the reduction of the development cycle as well as in the incorporation of agile practices in the model-driven workflow. Complete MDWE models can be built and generated by using lightweight modeling over User Interface mockups, and this process suggests being more efficient, in terms of errors and effort, than traditional modeling in MDWE.

Re-engineering legacy Web applications into RIAs by aligning modernization requirements, patterns and RIA features

Rich Internet Applications (RIAs) have become a common platform for Web developments. Its adoption has been accelerated thanks to different factors, among others, the appearance of patterns for typical RIA behaviors and the extension of different Model Driven Web Engineering methodologies to introduce RIA concepts. The real fact is that more and more developers are switching to RIA technologies and, thus, the modernization of legacy Web applications into RIAs has become a trend topic. However, this modernization process lacks of a systematic approach. Currently, it is done in an ad hoc manner, being expensive and error-prone. This work presents a systematic process to modernize legacy Web applications into RIAs. The process is based on the use of traceability matrices that relate modernization requirements, RIA features and patterns. Performing some operations on these matrices, they provide the analyst with the necessary information about the suitability of a pattern or set of patterns to address a given requirement. This work also introduces two measures, the degree of requirement realization and the degree of pattern realization, which are used to discuss the pattern selection. Finally, the applicability of the approach is evaluated by using it in several Web systems.

Quality evaluation for Model-Driven Web Engineering methodologies

ContextThere are lots of approaches or methodologies in the Model-Driven Web Engineering (MDWE) context to develop Web Applications without reaching a consensus on the use of standards and scarcity of both, practical experience and tool support. ObjectiveModel-Driven Web Engineering (MDWE) methodologies are constantly evolving. Moreover, Quality is a very important factor to identify within a methodology as it defines processes, techniques and artifacts to develop Web Applications. For this reason, when analyzing a methodology, it is not only necessary to evaluate quality, but also to find out how to improve it. The main goal of this paper is to develop a set of Quality Characteristics and Sub-Characteristics for MDWE approaches based on ISO/IEC standards. MethodFrom the software products context, some widely standards proposed, such as ISO/IEC 9126 or ISO/IEC 25000, suggest a Quality Model for software products, although up to now, there are no standard methods to assess quality on MDWE methodologies. Such methodologies can be organized into Properties, thus, a methodology has artifacts, processes and techniques. Then, each item is evaluated through a set of appropriate Quality Characteristics, depending on its nature. This paper proposes to evaluate a methodology as a product itself. ResultsThis paper recommends a set of Quality Characteristics and Sub-Characteristics based on these standards in order to evaluate MDWE methodologies quality. Additionally, it defines an agile way to relate these Quality Sub-Characteristics to Properties with the sole purpose of not only analyzing, but also assessing and improving MDWE methodologies. ConclusionsThe application of these Quality Characteristics and Sub-Characteristics could promote efficiency in methodologies since this kind of assessment enhances both the understanding of strengths and weaknesses of approaches.

From intentions to code: exploring the life of user goals in two web-based systems

Goal models have been found to be an effective way to represent, communicate and analyse stakeholder requirements. Once such models reach some degree of completeness, a software-intensive system is developed to support the achievement of the identified goals. A question that naturally arises in this process, though, is whether and how the way by which requirements are represented in goal models influences the structure of the design of the system to be built. Does the content and organisation of the resulting source code disclose anything about the stakeholder intentions that have led to its production, and how? In this study the authors focus on web-based systems and describe the experiences in developing two small, layered web applications using goal models as a requirements representation tool and without introducing any goal-model specific methodological, design or platform restrictions. The authors study the artefacts of this process in an effort to identify intentional categories to which different parts of the source code belongs. The results indeed suggest interesting characterisations of goals, source code and relationships thereof that could be useful in developing goal-oriented web engineering frameworks and methodologies.

Model Transformation from Ontology Model to Content Analysis Model

This paper introduces a technique to extend existing Web engineering methodologies to develop the semantic web applications. We investigate the use of ontology in the domain analysis for the development of web applications. The contribution of this paper is the automatic generation of Content Analysis Model from the Ontology Model. This technique makes a straight forward mapping between Ontology Definition Metamodel (ODM) model’s elements and the Content Analysis Model’s elements. We further show how this technique could be integrated with many web engineering methodologies, which are based on systematic and automatic chain of transformation during all the development phases. The requirement model that is generated from the Ontology model guarantees that an application terminologies are unified all over the web engineering process.

Engineering rich internet applications with a model-driven approach

Rich Internet Applications (RIAs) have introduced powerful novel functionalities into the Web architecture, borrowed from client-server and desktop applications. The resulting platforms allow designers to improve the user's experience, by exploiting client-side data and computation, bidirectional client-server communication, synchronous and asynchronous events, and rich interface widgets. However, the rapid evolution of RIA technologies challenges the Model-Driven Development methodologies that have been successfully applied in the past decade to traditional Web solutions. This paper illustrates an evolutionary approach for incorporating a wealth of RIA features into an existing Web engineering methodology and notation. The experience demonstrates that it is possible to model RIA application requirements at a high-level using a platform-independent notation, and generate the client-side and server-side code automatically. The resulting approach is evaluated in terms of expressive power, ease of use, and implementability.

Integrating usability requirements that can be evaluated in design time into Model Driven Engineering of Web Information Systems

In recent years, Web Engineering development projects have grown increasingly complex for and critical to the smooth running of organizations. However, recent studies reveal that a high percentage of these projects fail to attain the quality parameters required by stakeholders. The inadequate consideration of requirements management activities together with the absence of attention to the elicitation and evaluation of requirements and metrics related to certain quality attributes which are of special importance in this kind of systems, such as usability, have proved to be some of the main causes of this failure. This paper attempts to reduce some of the quality failures detected in Web Engineering development projects by proposing the consideration and evaluation of quality attributes from early stages of the development process. The presented approach therefore commences with a reinforcement of the requirements related activities in this discipline, which is carried out by using a requirements metamodel. Once these requirements have been identified, the approach focuses on the extension of the conceptual models used by Web Engineering methodologies with the aim of allowing the explicit consideration of usability requirements along with the evaluation of quality metrics during the design of the system. An example of an application illustrating how the approach can be used, along with the automatic support which was developed for it, are also shown.

Towards improving the navigability of Web applications: a model-driven approach

Navigability in use, defined as the efficiency, effectiveness and satisfaction with which a user navigates through the system in order to fulfil her goals under specific conditions, has a definite impact on the overall success of Web applications. This quality attribute can be measured based on the navigational model (NM) provided by Web engineering (WE) methodologies. Most of the measures currently defined for NMs are tightly coupled with particular WE methodologies, however. Furthermore, modifications to the design of the NM, carried out with the aim of improving navigability, are performed manually. Both practices have seriously hampered the reusability and adoption of proposed navigability measures and improvement techniques. In this paper, we present a Model-Driven Engineering approach to solving these problems. On the one hand, we propose a generic approach for the definition of navigability measurement models that can be integrated into any WE methodology. On the other hand, we present a model-driven improvement process for the NM design that incurs no increase in costs or in time-to-market of Web applications. This process is divided into two phases: evaluation (i.e. assessment of the model through objective measures) and evolution (i.e. transformation of the model when the measurement results do not fall inside the boundaries set by certain quality decision criteria that have been defined previously).

An Empirical Process for Evaluating and Selecting AWEM Environments: “Evaluation Stage”

This paper elaborates on the evaluation stage of an empirical process whose purpose is to evaluate and select a best-of-breed AWEM, Automated Web Engineering Methodology environment. The process is basically comprised of four major stages, namely: characteristics identification, screening of available AWEM environments, evaluation, and selection.During the evaluation stage, an “evaluation scheme”, which serves specific web application domains reflecting the organization's perspective towards the AWEM environment, is created. The idea is to make the evaluation process more user-centric. The actual evaluation is then conducted based on the results gained through the development of real pilot projects.The paper contributes to the current research in web engineering area by proposing an evaluation mechanism through the introduction of a so-called “evaluation scheme”, a sub-set of predefined essential criteria. Another major contribution is the introduction of an evaluation algorithm for weighing and rating various characteristics and alternatives that will eventually assist in making a final decision. Both, the process and the algorithm, were fully automated and evaluated on real world cases using the AWEM-ESS, which is an evaluation and selection system built specifically for this purpose.
