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.

Model Driven Approach

Many Web applications have among their features the possibility of distributing their data and their business logic between the client and the server, also allowing an asynchronous communication between them. These features, originally associated with the arrival of Rich Internet Applications (RIA), remain particularly relevant and desirable. In the area of RIA, there are few proposals that simultaneously consider these features, adopt Model-Driven Development (MDD), and use implementation technologies based on scripting. In this work, we start from MoWebA, an MDD approach to web application development, and we extend it by defining a specific architecture model with RIA functionalities, supporting the previously mentioned features. We have defined the necessary metamodels and UML profiles, as well as transformation rules that allow you to generate code based on HTML5, Javascript, jQuery, jQuery Datatables and jQuery UI. The preliminary validation of the proposal shows positive evidences regarding the effectiveness, efficiency and satisfaction of the users with respect to the modeling and code generation processes of the proposal.

With the advent of multitier and service-oriented architectures, the presentation tier is more detached from the rest of the web application than ever. Moreover, complex web applications can have thousands of linked web pages built using different technologies. As a result, the description of navigation maps has become more complex in recent years. This paper presents NMMp, a UML extension that: (i) provides an abstract vision of the navigation structure of the presentation tier of web applications, independently of architectural details or programming languages; (ii) can be automatically transformed into UML-WAE class diagrams, which can be easily integrated with the design of the other tiers of the web application; (iii) encourages the use of architectural and multitier design patterns; and (iv) has been developed according to OMG standards, thus facilitating its use with general purpose UML CASE tools in industry.

Model-driven methods are always welcome when developing complex applications. Their availability is usually related to the problem domain that has to be addressed and to the software architectures that have to be supported. Process-aware Web applications are arguably the prominent examples of applications in which multi-user, coordinated work takes place and are, as the web evolves towards a Business System, strongly emerging as one of the main types of Web-applications.In this chapter the authors propose a model-driven approach to process-aware Web applications based on a graphical process modeling and execution language that eases the development process (from the design to the implementation) by promoting an effective separation of concerns.Driven by an emerging class of applications, the Web is evolving into a Business System. Web-based business applications allow the participation of several actors to complex enterprise-wide (or even multi-enterprise) business processes and pose new challenges to the software designers and software architects. The design models have to address both navigational and process-based interactions; the software architecture has to provide the components to enact the process and has to define how these components interoperate with the other components of the Web applications. In this chapter the authors show how, promoting an effective separation of concerns, a process modeling language and its enactment engine can be used in the modeling and implementation of process-aware Web applications.

Many companies use the Web to communicate with the external world as well as within their organizations and to carry out their business processes more effectively. A survey on Web application development shows that 84% of development projects do not meet business needs, 56% do not have the required functionality, 79% are behind schedule, and 63% are over budget (Standish Group, 2002). García-Cabrera, Rodríguez-Fórtiz, and Parets-Llorca (2002) report that the development of a Web application is never finished, and the nature of Web applications is evolutionary. The architecture of Web applications has three layers: conceptual, presentation, and navigation. It also has two perspectives: designer and viewer. Software evolution is “the dynamic behavior of programming systems as they are maintained and enhanced over their life times” (Belady & Lehman, 1976). Web application evolution is of increasing importance as more Web systems are in production.

It is shown that the application of the Internet technologies is relevant in the selection of crop production technologies and the formation of a rational composition of the machine-and-tractor fl eet taking into account the conditions and production resources of a particular agricultural enterprise. The work gives a short description of the web applications, namely “ExactFarming”, “Agrivi” and “AgCommand” that provide a possibility to select technologies and technical means of soil treatment, and their functions. “ExactFarming” allows to collect and store information about temperature, precipitation and weather forecast in certain areas, keep records of information about crops and make technological maps using expert templates. “Agrivi” allows to store and provide access to weather information in the fi elds with certain crops. It has algorithms to detect and make warnings about risks related to diseases and pests, as well as provides economic calculations of crop profi tability and crop planning. “AgCommand” allows to track the position of machinery and equipment in the fi elds and provides data on the weather situation in order to plan the use of agricultural machinery in the fi elds. The web applications presented hereabove do not show relation between the technologies applied and agro-climatic features of the farm location zone. They do not take into account the phytosanitary conditions in the previous years, or the relief and contour of the fi elds while drawing up technological maps or selecting the machine-and-tractor fl eet. Siberian Physical-Technical Institute of Agrarian Problems of Siberian Federal Scientifi c Center of AgroBioTechnologies of the Russian Academy of Sciences developed a software complex PIKAT for supporting machine agrotechnologies for production of spring wheat grain at an agricultural enterprise, on the basis of which there is a plan to develop a web application that will consider all the main factors limiting the yield of cultivated crops.

Content is a key influencing factor in Web Quality of Experience (QoE) estimation. A web user’s satisfaction can be influenced by how long it takes to render and visualize the visible parts of the web page in the browser. This is referred to as the Above-the-fold (ATF) time. SpeedIndex (SI) has been widely used to estimate perceived web page loading speed of ATF content and a proxy metric for Web QoE estimation. Web application developers have been actively introducing innovative interactive features, such as animated and multimedia content, aiming to capture the users’ attention and improve the functionality and utility of the web applications. However, the literature shows that, for the websites with animated content, the estimated ATF time using the state-of-the-art metrics may not accurately match completed ATF time as perceived by users. This study introduces a new metric, Plausibly Complete Time (PCT), that estimates ATF time for a user’s perception of websites with and without animations. PCT can be integrated with SI and web QoE models. The accuracy of the proposed metric is evaluated based on two publicly available datasets. The proposed metric holds a high positive Spearman’s correlation (rs=0.89) with the Perceived ATF reported by the users for websites with and without animated content. This study demonstrates that using PCT as a KPI in QoE estimation models can improve the robustness of QoE estimation in comparison to using the state-of-the-art ATF time metric. Furthermore, experimental result showed that the estimation of SI using PCT improves the robustness of SI for websites with animated content. The PCT estimation allows web application designers to identify where poor design has significantly increased ATF time and refactor their implementation before it impacts end-user experience.

Nowadays, the Unified Modeling Language (UML) is the most successful notation for the design of object-oriented applications. However, plain UML is not enough to characterize the web presentation tier of enterprise applications, including the navigational, structural and role-based access control (RBAC) features present in these applications. In this paper, we present Enterprise Web Application Extension (E-WAE), a lightweight UML extension for the modeling of these elements, which permits the inclusion of multitier, Service-Oriented Architecture (SOA) and security design-level patterns in the models. Our approach follows a Model-Driven Development (MDD) approach, which enables the automatic generation of intermediate platform-specific models and automatic code generation for JavaServer Faces (JSF) and Active Server Pages.NET Model-View-Controller (ASP.NET MVC) frameworks. In addition, this generated code can be used as a low-cost mockup for early client validation of the navigational, structural and RBAC features of enterprise applications. E-WAE has been used with different applications. In this paper, we refer to the checkout process in the Amazon website, the delete resources use case in OdAJ2EE, an educational application developed by us, and the US Library of Congress Online Catalog search facility as examples of its applicability.
