Mark, Speaking of interesting ... i have just such a scenario i'm looking for options on. Design-wise what is clear at this point is that i have a primary BO that handles some properties, and a variable number of secondary BO's that handle language specific properties, depending on what languages are enabled in the app. Editing / updating is handled via a single form, so it all needs to hang together.
I'm not sure how to implement the DAO's here - or how the BO's should be related, but my impulse so far as the BO's are concerned would be composition, because there is a one to many relationship between the primary and secondary objects. I may be wrong tho' ... perhaps a manager class should contain and oversee the whole thing. If anyone has any suggestions, i'd be very grateful. Something simple, straightforward and obvious would be fine. I'm afraid i might tangle something together needlessly complex simply because i've never worked through this before. grazie, Nando -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mark Mandel Sent: Thursday, January 20, 2005 6:09 AM To: [email protected] Subject: Re: [CFCDev] Using queries to populate an object .... The stuff Nando posted is good - however, do note, that sometimes BO's can represent more than 1 row in a database on a single table, especially if they are composite of several other BO's - and then it can become interesting as to how you want to populate your Business Objects in DAO's. (And you can also get into a discussion on how to do things if you want to pull an array of BO's from a method, howabout you go about doing that - and even if you should...) Hope that helps somewhat.
