©Centre for Development of Advanced Computing 3 Current Set-up Low or no data exchange between various departments Computerization 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 format Each department has a separate front-end Citizen needs to visit and remember multiple locations for their various requests. No unified face of government

©Centre for Development of Advanced Computing 6 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

©Centre for Development of Advanced Computing 8 Who Will Benefit from SSDG? Government Departments Service Access Providers (Citizen Service Centre) Citizens
©Centre for Development of Advanced Computing 9 Government Departments Multiple delivery channels Better audit management & time stamping Web enabling of legacy applications Interoperability Departmental workflow Seamless availability of information Centralized management Shared services
©Centre for Development of Advanced Computing 10 Citizens Status tracking Grievance re-addressing at one point Data privacy maintained Single window service catering to multiple departments Allows the citizen to fill minimum data and fetches already available data under Unique ID from other departments Quick response to end user Keeps a record of each transaction in a secure manner and does not open the packet data (payload)
©Centre for Development of Advanced Computing 11 Service Access Providers Easy interface with departmental data & business logic Integrated and joined up services Flexibility in modifying the front-end application without touching the back-end applications

©Centre for Development of Advanced Computing Working with Connectors
©Centre for Development of Advanced Computing Application 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.
©Centre for Development of Advanced Computing Generic -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 Computing Generic -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.
©Centre for Development of Advanced Computing Application 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.

©Centre for Development of Advanced Computing 23 Service 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.)
©Centre for Development of Advanced Computing 24 Roles and Responsibilities of C-DAC Roles and Responsibilities of C-DAC C-DAC will provide SSDG software product C-DAC will also provide the optimized SSDG software stack containing: Operating System Application Server RDBMS
©Centre for Development of Advanced Computing 25 Roles and Responsibilities of C-DAC Roles and Responsibilities of C-DAC C-DAC will provide necessary patches, service packs and upgrades of SSDG over a period of 1+3 years C-DAC will provide technical support for SSDG product and the optimized Stack C-DAC will provide the training to the Implementation Agency (IA) and the state personnel.
©Centre for Development of Advanced Computing 26 Roles and Responsibilities of State Roles and Responsibilities of State State needs to sign an End User Licensing Agreement (EULA) with C-DAC before deploying the SSDG product. It is recommended to get the deployed SSDG solution certified by STQC as per ISO and standards. States should purchase the hardware subject to compliance with the Bill of Material (BOM) provided by C-DAC.
