Investigations on implementation of e-ATM Web Services based on .NET technique

1. Introduction

Web Service (WS) is a service designed to operate within machines to communicate over diverse networks (Catalina M. Llado, Ramon Puigjaner, Connie U. Smith, 2005). It is a server application that acts on server side and execute job when requested by an application. In the article “Web Services Architecture retrieved from web site: http://www.w3.org/TR/2002/WD-ws-arch-20021114” says that the Uniform Resource Identifier (URI) recognises WS, whose objects and bindings are self defined, described and exposed as Extensible Mark up Language (XML) object. It is a heterogeneous computing technology that offers interaction and collaboration among business community and customers (John B. Oladosu, Funmilola A. Ajala and Olukunle O. Popoola, 2005). The WS eases Business to Business (B2B) collaboration by incorporating compatible services to a large extends (Bora A., Bhuyan M.K and Bezboruah T., 2013). Application of WS reduces the time, cost constraints for discovering, discussing and running e-business communications (Chen Minder, Chen Andrew N.K. and Shao Menjamin B.M, 2003). The paradigm of WS could be the tactical model for success of next generation of Internet computation (Jia Zhang & Liang-Jie Zhang, 2005). A WS supports direct communication with other software applications using XML based messages via internet protocols only. It is based on three common protocols exclusively XML which includes: (a) the Simple Object Access Protocol (SOAP) for making communication between applications and information exchanges, (b) Web Service Description Language (WSDL), a format of XML which describes detail laid down procedures and access format of data and (c) Universal Description Discovery and Integration (UDDI), which is the central directory where available services are published.
