GuiController design

Hi guys. I'm using GuiController class to obtain data class reference and to perform operations needed for GUI like searching records or booking rooms. I can't make my DataRemote class to be DB(data class interface) , because of exceptions that are thrown in the DB interface.
So in the GuiControler class I have one reference to the Data class and other reference to the DataRemote. So in order to avoid many if statements I decided to make Connection class






How do you think about this approach ? Is it ok for the SCJD or should I rethink my design.

You can also use the Adapter pattern to adapt the remote interface to DB, or the other way round.

I'm not shure about Adapter pattern. Can you explain me in details how you would adapt the remote interface to DB ?

Well I believe what Alecsandru believed (let me know if I am wrong) is that you may be able to use the Strategy Pattern (Having the interface DB implemented on the directConnection and remoteConnection) and the Adapter Pattern together (Having an instance of directConnection inside remoteConnection and calling the methods from directConnection inside remoteConnection)
