Is there any way that I can connect to a server DB (Oracle, MS SQL, Sybase, ...) from a Windows Mobile application (written in C# using VS 2008). Is there support for say ODBC or another technologie? I'm connecting to a LAN via WLAN or via UMTS.
There is no possibility for me to install an additional server component.
Sure System.Data.SqlClient for SQL Server works just fine. For Oracle there's OraDirect.
No, the only direct connectivity option in CE is System.Data.SqlClient, which only works for SQL Server.
I've only done it using a purpose-built socket server - which has the benefit of enabling you to turn it into a useful abstraction layer, but is a medium-sized bit of work. Portable to any tcpip networkable client device, however. You can also then make it asynchronous which is almost required in a mobile environment.
