Current Set-upCurrent Set-up
Low or no data exchange between various departmentsComputerization without interoperability
If automated various departments may use different technologies, platforms, languages for developing their applications which may become a limiting factor in data exchange between departments
Data exchange in paper formatEach department has a separate front-end
Citizen needs to visit and remember multiple locations for their various requests. No unified face of government

What Is SSDG?
SSDG is a message X-change
Interoperable –
Helps any Service Access Provider (SAP) to Communicate with any Service Provider (SP) with appropriate authentication
IIP/IIS standards are developed to achieve this
XML based data
Secure
Authentication between SAP and services is achieved through mapping
PKI support
XML signature

ConnectorsConnectors
Designed for easy programming interface
Facilitate easy integration with SSDG
Ensure compliance to IIP (Interoperability Interface Protocol) and IIS (Interoperability Interface Specifications) messaging standards available in Java and .NET used by SSDG
Two types of connectors
Generic Connectors
Application Specific Connectors

Application Specific -SAPApplication Specific -SAP
Request from SAP to avail SP service will be sent through SSDG.Application Specific Connector will take the data from SAP and will convert the request as per the format understood by SP.Application specific Connector will use the API’s of Generic Connector to send the payload as per the IIP/IIS standards to the SSDG.Application Specific Connector will be developed by IAs.

Generic -SAPGeneric -SAP
Purpose of generic connector is to interface with gateway for standards based messaging communication.
C-DAC will be providing Generic Connectors.
Generic connectors are available in Java,. NET and php.
©Centre for Development of Advanced Computinghttp://ssdg.cdacmumbai.in
Generic -SPGeneric -SP
Purpose of generic connector is to check whether the message sent by SSDG is valid or not.
If the message sent is valid ,it passes the message to Application Specific Connector by extracting the payload and other necessary details.
If the message is invalid then it sends back the message to SSDG by populating necessary error codes.
C-DAC will be providing Generic Connectors.
Generic connectors are available in Java,. NET.

Application Specific -SPApplication Specific -SP
Based on the payload and details provide by generic connector, application specific connectors will send the request to SPs whose services are requested.Application specific connector will send back the necessary response to SAP through SSDG.Application Specific Connector will be developed by IAs.

Service Level of SSDGService Level of SSDG
Supports 50/100/250 messages per second (based on the BOM purchased by State)
95% of the transactions will a response time of 3 seconds else it will constitute a violation.(Note: Performance may vary depending on the Hardware Components used.)
