2 tier or 3 tier model?



I need to create a system where multiple users have simultaneous read /
write access to a SQL server database. I don't see anyway to connect
and notify each client that the table has changed without running a
requery() all the time. The event interface for ADO doesn't seem to
fire if someone else changes the underlying table. Do I need to add a
third tier and create a COM server to fire events to each client? Does
the third tier have to then handle all the database updates, deletes
etc... If so , what the heck good is SQL server. I can do the same
thing with an Access database.
