The DataMart Client may connect to multiple networks, multiple DataMarts within those networks, and multiple data sources. A typical data source is a  Postgres database in the pgAdmin application. Other database types, for example SQL Server or an Oracle database, are supported. 

The DataMart Client is a .NET/C# Windows desktop application developed which is installed locally on a DataMart Administrator’s desktop or a server environment.  All communications between the DataMart Client application and the Portal use HTTP/SSL/TLS connections to securely transfer requests and results between the desktop application and the Querytool/Portal.
