This is good information, but if you're going to do a POS deployment
that synchronizes data between multiple systems you really need to
understand the EntitySync stuff, and really the entity and service
engines in general. It is a powerful tool with lots of options, but
it also has some inherent limitations so you should understand the
nature of what it does and how.
The best resource for this right now is probably the new Advanced
Framework training materials that I just finished a few weeks ago.
You should start with the Framework Introduction, and there are links
from there to details about the advanced framework stuff:

Hello everybody
I have the following question about the POS module: how can I tell
this
module the address of the database server it must sync with? I've
read one
must check the file applications/ pos/data/PosSyncSettings.xml out to
configure the syncing between the server and the POS, but it
doesn't mention
anything about where the main database is (by 'main' I mean the
one that
opentaps uses). How can I set it?
Thanks in advance for your answer

Hi Ricardo,
This setting is intended to synchronise a main database (on the
Central - or Main - Server : MCS) with the databases of local stores
servers (PSS) each of them being synchronised with POS terminals.
Each of these OFBiz instances use a database. Store here means a
physical store where POS terminals are.
There is 4 types of flow :
MCS -> PSS
PSS -> POS
POS -> PSS
PSS -> MCS
where
MCS is a central OFBiz server (with one database, the central
database where all products information are are maintained and where
the consolidation is done)
PSS is an instance of a server store (with one database, the store
database where all store inventory information are stored)
POS is an instance of a POS terminal (with one database, the POS
database where all information)
the flow MCS -> PSS is used to update catalogs (from the central
database where the catalogs are maintained) of the stores. This
include roughly pricing, promotions, basic product info, etc.
the flow PSS -> POS is used to roughly update catalogs of the POS
terminals
the flow POS -> PSS is used to roughly update orders, payments ,
etc. of the store
the flow PSS -> MCS is used to roughly update orders, payments,
inventory, etc. in the main database.
This scheme is very powerful and help you to extend your net of
stores has needed. Remember that this is only an example and you can
extend it from your needs.
In the commented examples the MCS update the PSS hence POS catalogs
every 2 hours and the POS terminals update MCS database about
orders every 5 minutes .
This is at least how I see it. If I made a mistake, a core
developper will surely corrects me.
