Nemmadi Application
The Nemmadi application has been developed by Karnataka Unit of the National Informatics Centre (NIC), a Central government body under the Union Ministry of Information and Communication technology. Application is thick client and is PKI enabled.
The following diagram illustrates the Nemmadi Architecture
Salient features of current Nemmadi application architecture:
|
||
 |
|
Nemmadi application is a multilingual rich client that has been developed using.NET platform on Windows XP Professional platform. |
|
|
The architecture is N-tiered, scalable, secure and is based on the concept of a Service Oriented Architecture (SOA). |
|
|
Nemmadi application supports zero touch remote patch deployment where in internet kiosks can download the latest application and patch over internet. While the application is downloaded automatically, the administrator of the project can decide when will the updated application be put into use in different telecenters. This control on firing of the new features gives tremendous flexibility in launching new features. |
|
|
||
|
Nemmadi application supports multi-lingual user interface and data capturing |
|
|
||
|
Nemmadi application uses SQL Server 2000 Enterprise edition as backend at Taluk server and State Data centre. |
|
|
||
|
In the telecenters, Nemmadi application uses MSDE (scaled down free version of SQL Server) to store master and some config data. Such offline storage helps in avoiding frequent hits to database at SDC and Taluk server. |
|
|
||
|
Nemmadi application supports offline functionalities and uses MSMQ support provided by Windows XP professional to ensure durable, reliable, and secure and in order delivery of data related to offline mode requests. |
|
|
||
|
Every user can independently decide from where they want to work on pending request: either from village telecenter or from taluka center. |
|
|
||
|
Tele-Centers at village level connect to central hub at the State Data Centre (SDC) using a dedicated VSAT connection. The SDC connects to the Nemmadi back office at Taluka, again through a dedicated VSAT link. The Nemmadi back office at Taluka connects to local Taluka Server on a LAN. |
|
|
||
|
Tele-Centres connect directly to SDC to deliver eGovernance services and MIS reports. |
|
|
RDS application uses a custom communication framework based on .NET platform to ensure data between Taluk server and SDC are in sync. Custom framework has been developed to encapsulate data routing, transaction handling, in order & reliable delivery on low bandwidth. Unlike bandwidth hungry options like RDBMS based replication or log shipping custom communication designed for Nemmadi project uses less bandwidth and can take care of unreliable network and offline mode. Same custom communication framework would be used in future for other services also as it is scalable and extensible. |

System requirements:
Data tier (Database Layer)
Nemmadi project is designed to share the database server infrastructure deployed by GoK at State Data Centre (SDC) as central database and Bhoomi project Taluka level server for taluka level data.
As Bhoomi project and State data centre is running on SQL Server 2000 (running on Windows Server 2003 Server) Nemmadi application uses SQL Server 2000 for data storage at central, Taluka and Kiosk level.
Middle tier (Application layer)
On server side Nemmadi project is proposed to share the infrastructure deployed by GoK for State Data Centre (SDC) and Bhoomi project Taluka level server.
As Bhoomi project and State data centre is running on Windows Server 2000 / 2003 Server RDS application’s middle tier has been developed using .NET platform to take full advantage of existing investment of GoK.
Nemmadi application uses MSMQ 3.0, .Net based web services and server side components as middle tier.
Front end (Presentation Layer)
Front end application is developed using .NET platform and uses MSMQ 3.0; it requires Windows XP professional on client machine.
