Write notes on the following : (b) Vision of national service delivery gateway (NSDG)

The emergence of many e-governance applications for different departments to provide online services to citizens, businesses and government would require increasing interactions amongst departments and with external agencies at various levels in Government. Departments would need to develop connectors/adaptors for point to point connections between departments creating a mesh as shown in figure given below and also tight coupling between applications. This would lead to applications that are difficult to maintain and upgrade in case of version change and change in government policies and business rules. The NSDG is an attempt to reduce such point to point connections between departments and provide a standardized interfacing, messaging and routing switch through which various players such as departments, front-end service access providers and back-end service providers can make their applications and data inter-operable. The NSDG aims to achieve a high order of interoperability among autonomous and heterogeneous entities of the Government (in the Centre, States or Local bodies), based on a framework of e-Governance Standards.
