Abstract: This paper has been designed to identify the Web metrics for evaluating the design and effort estimation of hyperdocuments. In the age of Information and Communication Technology (ICT), Web and the Internet have brought significant changes in Information Technology (IT) and their related scenarios. Therefore in this paper an attempt has been made to trace out the Web-based measurements towards the creation of efficient Web centric applications. The dramatic increase in Web site development and their relative usage has led to the need of Web-based metrics. These metrics will accurately assess the efforts in a Web-based application. A study was carried out with the students of an advanced university class and Web designers that use various client-server based Web technologies to design Web-based application, and the objective was to calculate the reliability and maintainability of hyperdocuments. The first goal was to compare the relative significance of each design metrics. Second, it is tried to assess the accuracy of the assumed design metrics. Third, we promote the quality designs by capturing the dynamics involved in user behavior.
Keywords: Empirical software engineering, Web-based effort estimation, Web-based design, Web metrics.
Web-based application is essentially a client-server system, which combines traditional effort logic and functionality, usually server based, with the hypermedia navigation and data entry facilities provided by browser technology running on the client. Through a client Web browser, users are able to perform business operations and then to change the state of business data on the server. The range of Web-based applications varies enormously, from simple Web sites (Static Web sites) that are essentially hypertext document presentation applications, to sophisticated high volume e-commerce applications often involving supply, ordering, payment, tracking and delivery of goods or the provision of services (i.e. Dynamic and Active Web sites).
The focus in this paper is on the implementation and comparison of effort measurement models for Web-based hypermedia applications based on implementation phase of development life cycle. Various size measures to estimate the efforts at different points in the development life cycle of Web-based systems have been studied and compared based on several predictions. The main objective of design metrics is to provide basic feedback of the design being measured. There may be general lack of objects, polymorphism, inheritance, high level of coupling between the object classes or an uneven behaviour amongst the classes.
The major aim of this paper is to demonstrate an approach, which appears promising in terms of producing a direct assessment of Web-based metrics results. Web-based systems consist of the Web objects (i.e. Web documents, Images, Pictures, Sounds, Scripts, Active X Control). But developing good Web-based application is expensive, mostly in terms of time and degree of difficulty for the Web designers. In the present scenario, the companies developing Web-based systems face the problems and challenges of estimating the required development effort in a fixed time frame. This problem does not have a standard solution yet. On the other hand, effort estimation models that have been used for many years in traditional software development are not very accurate for Web-based software development effort estimation . Moreover, the rapid evolution and growth of Web related technology, tools and methodologies makes historical information and effort estimation models of software engineering quickly obsolete. Like any other software process, Web application development would benefit from early stage effort estimation. Keeping the above-mentioned requirements in mind, a number of activities have been carried out involving study of Web-based systems by using practical and theoretical analysis. Efforts have been made to understand the design specifications, and develop the corresponding Web-based modules by using client-server technologies of Web design     . The modules have been designed to work in client-server and stand-alone modes under different environment.
