Hi!

Has anyone made or used or seen a TCustomProvider descendant that can
retrieve data from and post updates back to a Business Object?

How would you value such setup where there is one provider available
for each business object class, that mediates communication between
user interface and BO, creates and loads objects when needed and so
on? User inteface layer could specify what business objects to use via
its params property. Would you use TDataSetProvider and embed a
dataset in BO that provider will use or would you build/find some
custom provider?

Or is it better when UI communicates with BO-s directly? And BO-s have
methods
loadClientDatasetWithPublicData (ds:TDataset)
and
saveUpdatesFromDataset(ds:TDataset)

or ... ? How would you solve this?

Thank you!
