Hi kat:
Yes, in general the request is going to flow through each tier in a
single thread or flow of control. The website as a whole doesn't
necessarily 'pause' while this happens - the website can service
multiple requests and each request will process through the tiers to
come up with some results.
In more advanced distributed applications the flow can branch into
multiple operations and some processing can take place asynchronously
or be queued to perform at a later time.

Hi,
I am pretty new to understanding how distributed applications work, and I
just want to understand the flow of a single request. When a request is made
that requires information from n-tiers, does the website pause to wait for it
to go to all the tiers? So if a request had to make multiple queries to a
database on a different system would all those queries have to complete
before the request would return?
Thanks,
kat
