Need some clarification with Patterns (DAO x Gateway)
- by Marcos Placona
Me and my colleagues got into this discussion early this morning, and our opinions started to clash a bit, so I decided to get some impartial advice here.
One of my colleagues reckons that the DAO should return an object (populated bean). I think it's completely fine when you're returning a recordset with only one line, but think it's overkill if you have to return 10 lines, and create 10 separate objects.
I on the other see that the difference between DAO and Gateway pattern is that the gateway pattern will allow you to return a recordset to your business class, which will therefore deal with the recordset data and do whatever it needs to do.
My questions here are:
Which assumptions are correct?
What should the return type be for a
DAO (i.e. getContact() - for one record)
Should getContacts() (for multiple records) even be on the
DAO, if so, what's it's returntype?
We seem to be having some sort of confusion about DAO and Gateway Patterns. Should they be used together?
Thanks in advance
