A Web service is a self-describing, self-contained software module available via a network, such as the Internet, which complete tasks, solves problems, or conducts transactions on behalf of a user or application.[Papazoglou, 2007]
_ALT_
A Web Service is a service provided by a software system that implements a predefined set of standards. It is designed to support interoperable machine-to-machine interaction over a network. It has a service description (called interface) described in a machine-processable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP-messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards. [CD-IA-1.1.1]
