The widespread use and expansion of the World Wide Web has revolutionized the discovery, access and retrieval of information. The Internet has become the doorway to a vast information base and has leveraged the access to information through standard protocols and technologies like Hyper Text Markup Language (HTML), Active Server Pages (ASP), Java Server Pages (JSP), Web databases and Web services. Web services are software applications that are accessible over the World Wide Web through standard communication protocols. A Web service typically has a Web accessible interface for its clients at the front end, and is connected to a database system and other related application suite at the backend. Thus Web services can render efficient Web access to an information base in a secured and selective manner. The true success of this technology, however, largely depends on the efficient management of the various components forming the backbone of a Web service system. This chapter presents an overview and the state-of-the-art of various management approaches, models, and architectures for Web services systems towards achieving Quality of Service (QoS) in Web data access. Finally it discusses the importance of autonomic or self-managing systems and provides an outline of our current research on autonomic Web services.

A web service is a service offered by a device electronically to communicate with other electronic device using the World wide web. Smartphone is an electronic device that almost everyone has, especially student and parent for getting information about the school. In BINUS School Serpong mobile application, web services used for getting data from web server like student and menu data. Problem faced by BINUS School Serpong today is the time-consuming application update when using the native application while the application updates are very frequent. To resolve this problem, BINUS School Serpong mobile application will use the web service. This article showed the usage of web services with XML for retrieving data of student. The result from this study is that by using web service, smartphone can retrieve data consistently between multiple platforms.

The term “Web services” was initially employed by Bill Gates, chairman of Microsoft, at the Microsoft Professional Developers Conference in Orlando, Florida on July 12, 2000. Fundamentally, the term refers to automated resources accessed via an Internet URL. However, a more comprehensive definition is that of the World Wide Web Consortium (W3C)1, which declare Web services as “providing a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks.” An Internet connection allows retrieval of software-powered resources or functional components and is therefore regarded as an extension of the World Wide Web infrastructure. Web services represent the evolution of a human-oriented utilization of the Web to a technology that is application driven. It attempts to replace human-centric searches for information with searches that are primarily application based (Staab, 2003).

The Broker Architecture became popular involving client and server. Representational State Transfer(REST) architecture is the architecture of World Wide Web. REST uses HTTP protocol based on Servlet and ASMX technology is replaced by WCF web service technology. SOAP and REST are two kinds of WCF web services. REST is lightweight compared to SOAP and hence emerged as the popular technology for building distributed applications in the cloud. In this paper, conducted by exposing a HTTP endpoint address, HTTP relay binding (webHttpRelayBinding) and CRUD contract through interface. The interface is decorated using WebGet and WebInvoke attributes. WCF configuration file created using XML tags for use with REST web service.


Replication [7] must work. In fact, few cyberneticists would disagree with the signifi-cant unification of the lookaside buffer and I/O automata, which embodies the practi-cal principles of Bayesian complexity theory. In order to solve this question, we describe a novel methodology for the deployment of object-oriented languages (YAMP), discon-firming that the World Wide Web and robots can collude to realize this intent.

Chapter II presented the main concepts underlying business services. Ultimately, as this book proposes, business services need to be decomposed into networks of executable Web services. Web services are the primary software technology available today that closely matches the characteristics of business services. To understand the mapping from business to Web services, we need to understand the fundamental characteristics of the latter. This chapter therefore will introduce the main Web services concepts and standards. It does not intend to be a comprehensive description of all standards applicable to Web services, as many of them are still in a state of flux. It focuses instead on the more important and stable standards. All such standards are fully and precisely defined and maintained by the organizations that have defined and endorsed them, such as the World Wide Web Consortium (http://w3c. org), the OASIS organization (http://www.oasis-open.org) and others. We advise readers to visit periodically the Web sites describing the various standards to obtain the up to date versions.

A Web service is a software system that supports interoperable application-to-application interactions over a network. Web services are based on a set of XML standards such as Universal Description, Discovery and Integration (UDDI), Web Services Description Language (WSDL), and Simple Object Access Protocol (SOAP). Recently, there have been increasing demands and discussions about Web services privacy technologies in the industry and research community. To enable privacy protection for Web service consumers across multiple domains and services, the World Wide Web Consortium (W3C) published a document called “Web Services Architecture (WSA) Requirements” that defines some fundamental privacy requirements for Web services. However, no comprehensive solutions to the various privacy issues have been so far defined. For these reasons, this chapter will focus on privacy technologies by first discussing the main privacy issues in WSA and related protocols. Then, this chapter illustrates the standardization efforts going on in the context of privacy for Web services and proposes different technical approaches to tackle the privacy issues.

- public broadcasting's Web site visited by more than 2,000 users a day - as its test-bed for research and field-testing of solutions. The Web Access Project is made possible by the support of the Telecommunications Funding Partnership for People with Disabilities, and The Boston Foundation. This paper will describe NCAM's prototype method for captioning QuickTime video clips. The current technology employed is Apple Macintosh-based only but the captioned movies operate on either Macintosh or PC platforms. It is important to note that the procedures described in this paper represent solutions still under development. They are likely to change as technology improves.

The advent of technology is reshaping the landscape of political campaigns. Cable television, satellite uplinks, cellular telephones, facsimile machines, and related communications and software applications offer ever more sophisticated ways of reaching voters. With each passing month, the advertisements in Campaigns and Elections, the trade journal of consultants and political professionals, are filled with more applications of this new information and media technology. Simply collecting and keeping track of the advertisements of a rival during a campaign is now a large part of the work of a campaign. Where candidates once coveted relationships with voters in their districts, they now purchase lists of these same voters on CD-ROM and data files on the World Wide Web as a part of the new campaign technologies.
