Web-Services Architecture: The Solution For E-Government Applications

Last few years, several projects under the Egovernment initiative have emerged; they are aiming to bring public administration such as for i.e. taxation service, closer to citizens and industrials. Today most of governments are aware that the use of information communication tools represents a powerful means to increase collaboration and cooperation between different public institutions. The aims are to provide better and more efficient services to citizens. The ambitions of governments are to facilitate and encourage development of homogenous web-platforms providing to citizens just with one single authentication, access to several public services such as taxation service, social service, health care, etc. However most of the governmental bodies are running their own information systems and connecting them together is not an obvious task. The main challenge relies on integrating efficiently all those heterogeneous public information systems by providing a unified environment. Our project intends to define an integration applications model based on service oriented architecture (SOA). The project is based on real enterprise information systems developed and maintained by a Norwegian public organisation.
