NX (Contractors).. DBAccess, Data, and DataAdapter Dilemma

[Majid AlMeshari]

Hi Everyone,
I just started the new assignment (Contractors), before that I completed the indispensable Max's book.
The Dilemma I'm facing at the moment is a Sun's requirement thing. The requirements say:
"Your data access class must be called "Data.java", must be in a package called "suncertify.db", and must implement the following interface..."
does this mean that the class that handles the DB I/O must be Data.java?
Or , as Max advises, we can declare a DB I/O calss that handles the I/O without impliementing the DBAccess Interface?.
Between trying an elegant solution and sticking to the requirements, there is a fine thin red line. You cross it and you fail automatically.

IMO, this means the class that handles at least the IO in the interface must be in the Data class.

Hi Majid
Welcome to JavaRanch.
Your requirements do not state that all IO must be done through the Data class. You could have another class doing IO which Data calls as required.
If you do this, you just have to make sure that the Data class is the class that the rest of your application calls to access the database - they must not call (or even know about) your other class which is doing the low level work.
