ASP.Net - Can ASP.Net Communicate with Databases other than SQL Server?

Yes.

Out of the box, ASP.Net ships with the ability to communicate with SQL Server, through the System.Data.SqlClient Namespace:

However, you are not prevented from attaching to other databases. For instance, this can either be achieved through the use of an ODBC connection to the database.

However, the majority of the major database manufacturers provide their own implementation for easily connecting to their databases through a provider. You can find a list of the available providers here:
