I am using FireBird Database as my Back end for my Window Application
BUT I need to sync my PPC app to the database. How can I sync my PPC app database to the FireBird database
2.
Can I Access the Firebird database via a DSN connection from the Mobile Device?
You can only work directly with a SQLite database.
You can connect to a server / client database with some web service that will run on the server and will do the actual connection.
