Web engineering is a systematic approach to develop web applications, and numerous web engineering methods have been proposed. These methods were extended through defining new models by using different mechanisms to capture the web application concepts. Due to the complexity rising of web applications, the web engineering methods cannot provide web solutions anymore. Even though Interaction Flow Modeling Language (IFML) is recently proposed as a new method for developing web applications, it has limitations. Therefore these methods need to be improved. In this paper, we present the ability of IFML extensibility to support new concerns from web applications. Moreover, we extend IFML through UML mechanisms to support new concerns from the context to the user interface. The new IFML solves the lack of context web application through defining a new model and becomes a new direction to develop concerns modern web applications.

Development Approach

Development and deployment technologies for data-intensive web applications have considerably evolved in the last years. Domain-specific frameworks or model-driven web engineering approaches are examples of these technologies. They have made possible to face implicit problems of these systems such as quick evolving business rules or severe time-to-market requirements. Both approaches propose the automation of redundant development tasks as the key factor for their success. The implementation of CRUD operations is a clear example of repetitive and recurrent task that may be automated. However, although web application frameworks have provided mechanisms to automate the implementation of CRUD operations, model-driven web engineering approaches have generally ignored them, so automation has not been properly faced yet. This paper presents a pattern-based development approach for the Interaction Flow Modeling Language as a way to finally automate repetitive specification tasks. Our approach is illustrated by defining and applying IFML patterns for CRUD operations. Additionally, a supporting tool, which enables automation, is shown. The suitability of our approach and the utility of its tool have been evaluated by its application into several real projects developed by a software company specialized in model-driven web application development. The results obtained present evidence of a significant productivity improvement obtained by the automation of the IFML specification of CRUD operations.

Modelling Approach

SummaryTask modelling has entered the development process of web applications, strengthening the usage-centred view within the early steps in Web-Engineering (WE). In current approaches, however, this view is not kept up during subsequent activities to the same degree as this is the case in the field of Human-Computer-Interaction (HCI). The modelling approach presented in this contribution combines models as known from WE with models used in HCI to change this situation. Basically the WE-HCI-integration is supported by combining task and object models as known from HCI with conceptual modelling known from WE. In this paper, the main focus is on the WebTaskModel, a task model adapted to web application concerns, and its contribution towards a task-related web user interface. The main difference to existing task models is the build-time and run-time usage of a generic task lifecycle. Hereby the description of exceptions and erroneous situations during task performance (caused by, e.g., the stateless protocol or Browser interaction) is enabled and at the same time clearly separated from the flow of correct action.

The requirements phase of the system/application development process typically involves the activities of requirements elicitation, analysis, validation, and specification. The main goal of such a process is “to develop a requirements speci- fication document which defines the system to be procured and which can act as a basis for the system design” (Sawyer, Sommerville, & Viller, 1996). Hence the underpinning assumption of the requirements engineering (RE) process is to transform the operational needs of an organisation into complete, consistent, and unambiguous system/application specifications through an iterative process of definition and validation (Pohl ,1994). The Web engineering (WE) literature provides a limited number of methods and techniques that can be used to manage the RE process in a Web development context [e3-value framework (Gordijn, Akkermans, & van Vliet, 2000), SOARE approach (Bleistein, Aurum, Cox, & Ray, 2004), e-prototyping (Bleek, Jeenicke, & Klischewski, 2002), AWARE (Bolchini & Paolini, 2004), and SSM/ICDT (Meldrum & Rose, 2004)]. Despite the availability of such a limited number of Web requirements engineering (WRE) methods, many researchers criticised such methods for their failure to address the necessity to align the Web application’ requirements to the organisation’s business strategy. Hence, the recommendation of many researchers (Al-Salem & Abu- Samaha, 2005a; Bleistein 2005; Bleistein, Cox, & Verner, 2004; Vidgen, Avison, Wood, & Wood-Harper, 2002) is to utilise a general WRE framework for the development of Web applications that can align the application’s requirements to the organisation’s business needs and its future vision. The objective of such a WRE framework is to incorporate the elicitation/analysis of business strategy as part of the application’s RE process. This chapter presents a WRE method that extends Sommerville and Kotonya’s viewpoint-oriented requirements definition (VORD) and Kaplan and Norton’s balanced scorecard (BSC) to elicit the Web application’ requirements and to plan/analyze the business strategy, respectively. In addition, eWARE (extended Web application requirements engineering) deploys the concept of “requirements alignment” to attain business objectives during the requirements discovery, elicitation, and formalisation process to identify the services of the Web application that will achieve the business objectives in order to improve the organisation’s profitability and competitiveness. The chapter is organised into a number of sections. The second section of this chapter provides a background to Web applications in terms of defi- nition and differentiating characteristics. The third section provides a discussion of eWARE method in terms of phases and activities. This section is divided into two subsections to cover the activities of the two prominent phases of the eWARE process in more detail. The fourth and fifth sections provide a discussion of possible future trends in WRE and a number of concluding remarks.

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.

SummaryPortlets are Java technology based web components, managed by a portlet container, that process requests and generate dynamic content. They are used by portals as pluggable user interface components that provide a presentation layer to Information Systems. After servlets portlets are the next step in web application programming, as they allow the integration of different applications into one consistent view for the end-user. They enable modular and user centric web applications and thus go beyond the servlet model where the web application is one monolithic block. In this article we present the JSR 168 Java Portlet Specification and explain its underlying concepts. We show a Portlet example and discuss how portlets interact with other Java technologies.

The Way

The last decade has seen remarkable changes in the way Web applications are developed and the services that are expected from them. The desire to control and manage the size and complexity of Web applications has led to a systematic approach for creating them that is known as Web engineering (Ginige & Murugesan, 2001). A focus on the "essence" rather than "accidents" is crucial to any engineering (McConnell, 1999). The engineering environment of Web applications is in a constant state of technological and social flux. New implementation languages, variations in user agents, demands for new services, and user classes from different cultural backgrounds and age groups, are faced by the Web engineers on a regular basis. For sustainability and evolvability of Web applications, it is critical that they be based upon domain, time- and technology-independent bodies of knowledge. One such invariant is the set of principles that forms the foundation of Web engineering.

Important Milestone

Model-Driven Web Engineering (MDWE) approaches aim to improve the Web applications development process by focusing on modeling instead of coding, and deriving the running application by transformations from conceptual models to code. The emergence of the Interaction Flow Modeling Language (IFML) has been an important milestone in the evolution of Web modeling languages, indicating not only the maturity of the field but also a final convergence of languages. In this paper we explain the evolution of modeling and design approaches since the early years (in the 90’s) detailing the forces which drove that evolution and discussing the strengths and weaknesses of some of those approaches. A brief presentation of the IFML is accompanied with a thorough analysis of the most important achievements of the MDWE community as well as the problems and obstacles that hinder the dissemination of model-driven techniques in the Web engineering field.

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.

As we know internet has become a very important factor in our day today life. It is a wide media for communication and exchange of ideas for people staying in any nook and corner of the world. We have proposed a system in which we are developing a speech interactive web application services. Our main aim is to provide these services to the special ones who are unable to make use of the current system so efficiently. In our proposed work we are mainly focusing on the WEB APPLICATIONS. Many a times the disabled people are unable to access internet, for them this system will help to download news, or even access their mails through speech. Our proposed system mainly deals with the ability to handle web applications along with the O.S, mouse and keyboard control through speech, so that they can be used by persons without the use of the hands to develop an interface between the computer and the user. In our proposal we have used SAPI .It provides commands to the main central application which is handled by the GUI. Thus we look forward to develop web application through speech interaction.
