[SQLObject] Sobject and validating via schema objects.

[David D. <cou...@gm...>]

I am trying to figure out the best way to organize this. I have a
sqlobject "Customer" and a validator schema CustomerSchema. I want the
application to be able to use sqlobject  directly so I don't have to
do anything to wrap up the object traversal. Java programming would
wrap sqlobject with another object that contains the domain logic and
getters+setters etc to get some seperation between the application and
the persistence object. Since I want the application to use the
sqlobject directly I need to decide on how to interject validation and
other DO logic.

What I am looking at now is an object that be something like
"CustomerUpdater."  This would receive the object that needs to be
updated and a dictionary that maps keys  to new values. This would be
called by the application. The updater would pass values from the
updated dictionary and values in the sqlobject to the validator schema
doing field level validation then doing chain validation. If
everything validates update the sqlobject. If it doesn't return a
dictionary or list of fields that didn't validate and the sqlobject
remains unchanged.

I have drawn this on the whiteboard several times and this is the
closest that I can get to making sense out of what I want to do.

Does it make sense to anyone else?
