The eGovernment solutions are widely supported by Web Services as a way for agencies, other governments, businesses and citizens to make queries and discover the interoperable information available in their systems. A Web service is implemented as an application that exposes a function accessible using Web technology that adheres to Web services standards. This is a significant feature since Web services are developed for and deployed onto any platform using any programming language. In practical terms, Web services can announce themselves across the Internet and expose their functionality to other applications.
