Comparative Study of Mechanisms for Web Service Discovery based on Centralized Approach Focusing on UDDI

Abstract

service is a set of related application methods that can be accessed programmatically over the Internet. Businesses can dynamically mix and match Web services to perform complex functionality with minimal programming. Web services allow buyers and sellers all over the world to find each other, connect dynamically, and execute transactions in real time with minimal human interaction. Web services are self-contained, self-describing modular applications that can be published, located, and invoked across the Web. While creating web applications using web service technology there is a need for selecting new web services which best suit our need at the moment. For doing this we require to specify our criteria for selection of web service. Apart from this, appropriateness and optimality are the challenging issues at the time of web service consumption. Web services are important for interoperability of applications and integration of large scale distributed systems irrespective of platform. Web service discovery mechanisms are equally important, especially as the latter has turn to be difficult task. This paper reviews the latest mechanism, techniques, architectures and models that have evolved in the web service discovery area.
