hello!!  There was this friend of mine using VB.NET and he's having a hard time doing update on
a "concurrency" thing.  He explained to me that he's problem was how to update a record being updated
by 2 or more than users,  he was doing a "disconnected dataset".

	He told me that in large companies wherein there will be a lot of users who will be accessing
database, they recommend using "disconnected dataset" to avoid overload on the server machine.
Is this true?  but how would you have data integrity if 2 or more users updating the record at
the same time?  Would there will be a problem if this disconnected datasets if synchronized already
on the dbase?

	Any idea that you can share?  I haven't encountered large databases containing million of records
and used by a lot of users.  What was the setup for this large scale databases?	

Thanks,
