I am a beginner with scala/lift and POO. In the beginning, i must produce a database and a straightforward interface to sign in (ID and password). Then create a credit card applicatoin to permit the consumer to change this database.

My issue is: i did not find anything (just like a tutorial) to behave like this.

Maybe somebody may help?

DB.defineConnectionManager(DefaultConnectionIdentifier, DBVendor)
