Each database library will have its own database-specific API. The Rails database adapters hide these differences so that a Rails application doesn’t need to know what kind of database it is running on.

If you’re still reading this, it means you want to connect to a database other than MySQL. Rails works with DB2, MySQL, Oracle, Postgres, Firebird, SQL Server, and SQLite.
Anything past this in the incoming URL will not change that—the same application will still be invoked.
