As a result of their dynamic nature, perceptive interface features, large and heterogeneous audience, and navigational access to information Web based applications are engineered differently from other Information System. Our approach works closely with the Web specific functional and non-functional Requirements and delivers models with lesser conflicts, better choice amongst alternatives and handles crosscutting concerns for modeling personalization and non-functional requirements. We have enhanced and extended User Requirements Notation to meet the Web specific needs. We also propose a systematic approach for automatically constructing the Web specific GRL diagrams.

Off late, the quality of air in urban places has been found unfavorable and Delhi is no exception for this. The National Air Quality Standards have stressed that the main pollutants are particulate matter (PM). A thorough analysis of past years of quality of air in Delhi-NCR has been done by us for certain areas, and broadly, the analysis results of air quality data have revealed that the Air Quality Index (AQI) was high during the winters, low during the monsoons and average during summers. This analysis has been done for identifying the variations in the air quality and their effects on human health. We have further applied this data to an algorithm to predict the future air quality results with great accuracy so that in future the predicted data can be used for taking measures to control air pollution and prevent the hazards resulting from the same. This paper has considered the air quality data for the three most polluted areas of Delhi, i.e. ITO, Anand Vihar and Jahangirpuri at Delhi. If we can predict the future air quality in a given area, then the major issues of air pollution can be curtailed beforehand so that the critical health-related issues can be prevented.

The first step is to capture the requirements comprehensively both explicit and implicit requirements. Further, in order to ensure a smooth conversion of comprehensive description of the requirements we need a design model that can handle the requirements captured earlier in totality. For this we need a design model that has the ability to present the different perspectives of a web application holistically. Therefore a new enhanced EAOO-H design model is presented in this paper that can capture both explicit and implicit requirements with the help of different web specific design models namely the content, navigation and the presentation models. These web specific models form a very important part of structured modeling of web applications. Therefore, we need to ensure that these web specific design models are such that they aid the conversion strategy from the requirements stage to the design stage and further convert easily into ...

Goal oriented approaches are preferred over other requirements engineering approaches for their capability to reason about the requirements and evaluate different solutions. We have enhanced and customized the goal driven reasoning approach for engineering Web applications. Our work is based upon a standard, User Requirements Notation (URN) that has been enhanced by us to suit the Web applications domain and termed WebURN. For different kinds of Web applications and level of domain knowledge, a suitable reasoning approach i.e. Qualitative or Quantitative can be chosen.We have focused on qualitative reasoning methodology in this paper, wherein subjective satisfaction values and contribution values are applied for evaluating the WebGRL graphs. Comparison with other approaches yields that this qualitative approach is more precise, resolves conflicts au...

Web engineers mostly focus on design aspects only overlooking the real goals and expectations of the user. Goal oriented Requirement Engineering is a popular approach for Information system development but has not been explored much for Web applications. However, in today's times Web is dominating in every business making it imperative that its requirements are analyzed carefully and in profundity. Goal driven requirements analysis helps in capturing stakeholders' goals very finely, by choosing between alternatives and resolving conflicts. Detailed classification of both functional and non-functional requirements specific to web applications is discussed in the presented work. A framework, GOREWEB (Goal oriented Requirements Engineering for Web Applications) is proposed for analyzing goals and translating them into functional and non-functional web requirements.

Goal Oriented Requirement Engineering is a popular approach for Information system development but has not been explored much for Web applications. Goal driven requirements analysis helps in capturing stakeholders’ goals very finely, they enhance the requirements analysis in many ways, as the requirement clarification and the conflicts between requirements can be detected at an early stage and design alternatives can be evaluated and selected to suit the require ments. In this paper, we take a step from the requirements phase to the design phase. While adheringto the web based goal oriented requirements engineering in the first phase we move to the A-OOH design models using a model transformation strategy to derive web specific design models supported by a UML profile. This helps i...

We formalize the transformation technique by using the graph theoretic notion of isomorphism. Method concepts are organized in an is built of method graph. The generation technique is used to establish isomorphism between the concepts of the two graphs by generating nodes and edges. This technique produces feasible mappings, which can be presented to the method engineer for subsequent fine-tuning. The technique is illustrated for mapping between ER and Relational models. It is a soft approach as it allows the method engineer to accept or make modifications as per his requirement.

The work is based on Web specific User Requirements Notation (WebURN), which is an enhancement of a goal and scenario based standard, User Requirements Notation (URN). We present the forward reasoning approach for finding the satisfaction level of the root/parent goals from the sub-goals in the goal model. The Quantitative Reasoning method called Forward Reasoning and Evaluation: Numeric (FREN) is apt when enough domain knowledge is there and precise results are expected. We propose a Quantitative Reasoning and Evaluation approach in this paper wherein the requirements engineer has an estimate of the satisfaction level of tasks and knows the priorities of various goals and sub-goals. The rules for propagation of satisfaction values from the leaves to the root level goals are specified in detail. The approach is then applied to the Web-specific Goal driven Requirements models for evaluation. The methodology has been implemented in the WebURN tool, built upon Microsoft Visio for editing and analyzing the WebURN diagrams. The results of evaluations are also compared with other prominent approaches in the area of Goal oriented Requirements Engineering. The methodology used for evaluation enables choice amongst design alternatives, resolves conflicts automatically and incorporates the role of priority in making design decisions.

All the three concepts have been playing important role independently in requirement modeling in the last decade. Goal based approaches have been very popular as they give in depth understanding of stakeholders intentions and scenarios give detailed walkthroughs of the system. Aspect oriented Software Development is another area booming in software modeling because it caters the modeling of crosscutting concerns. In web applications the specific cross cutting concerns are personalization requirements, non-functional requirements. Web applications are the principal software for every organization, therefore their in-depth analysis is crucial. Besides, web applications need to be dealt differently from generic information systems, which arguably give a need to develop different modeling and analysis approaches. Our approach is based on AoURN (Aspect Oriented User Requirements Notation), that is based on a International Telecommunications Union Standard called URN that was standardized in November 2008. We adapt and modify this notation to suit the web specific needs.

It has thus become important to engineer these applications methodologically. Goal integration from the early stages maximizes the product quality and prevents giving "requirements" amiss. We propose a Goal based Requirement Analysis for creating the web application. Both functional and non-functional requirements have been studied specific to the web applications. The requirements can be analysed according to the type of application being constructed. The web classification model aids in the understanding of web applications.

Method concepts are organised in an is composed of hierarchy. A technique is presented that maps concepts of one hierarchy to those of the other. This technique produces feasible mappings, which can be presented to the method engineer for subsequent fine-tuning. The technique is illustrated for mapping between ER and Relational as well as between Relational and XML models respectively.

In order to provide an insight into the existing transformation approaches, to draw out the practicability and analyze the strengths and weaknesses of these approaches a multidimensional classification is required. In this paper, a classification framework is proposed which provides a multidimensional, faceted and measure based viewpoint to give a clear and better insight into the existing model transformation approaches.
