You know, maybe the second part of the question was not correct. Thanks that
you corrected me.

What about the first question? If you receive data from a few database
tables using subqueries, JOIN, many other tricks, then do you parse this
information to your custom objects loading the whole data into your own
object and then deleting the original DataSet? Ok, I can imagine that, but
if you need to save the changes, made by user, then you need to compare what
has been changes, so you need flags in every sub object to detect if this
data is dirty and finally write this data? What do you think if you use a
database view to retrieve this complex data instead and save data back to
this view? In this case you could use the same DataSet to show and save a
changed data and use DataAdapter.Update() any headache. Is it good or bad?
Or I don't see something obvious? Maybe the custom objects are always
better?

Thanks,
Dmitri
