RE: Data Queues Beginner Question

["Richard B Baird" <rbaird@xxxxxxxxxxxxxxxxxxxxx>]

Buck, Justin,

Correct me if I'm wrong, but the scenario you (buck) describe, would be
more complicated than need be, if the client and the server were on the
same box, because wouldn't it be quicker and easier to just write a
procedure or external call to retrieve the quantity?

Plus, if i remember correctly, aren't there data queue hooks for other
platforms (windows, *nix, java, etc.) that were being pushed for the
classic client/server model?

Sure.  Think of data queues as messengers.  On the one end you have a
client
who needs to know the on hand quantity.  So he puts a message on the queue
with the part number.  Then you have a server program you wrote who is
listening to that queue.  When he hears the message, he does the lookup and
returns the quantity by putting a message on another queue (or the same
one.)  You can make the queues 'keyed' so that the two ends of the
transaction share a common ID number.

client: send ID 541, part ABC
server: recv ID 541, part ABC
        look up ABC
        send ID 541, part ABC, qty 34
client: recv ID 541, part ABC, qty 34
