You don't need touchscreen to use the POS, nor Webpos of course The main difference between Webpos and POS is you can't use JavaPOS
devices with Webpos. Also they have not exactly the same features at the UI level.
Option 1 (each till has its own DB) is safer at 1st glance but need a consolidation using Entity Sync
https://cwiki.apache.org/confluence/display/OFBIZ/Sync+Setup+Notes+and+Example. It works, but is not obvious to settle and use. On
the other hand, if you are on a local network, accessing a sole DB is relatively safe and certainly easier (no need to worry about
syncing). Of course this needs a reliable LAN. Performance should not be an issue. In other words if you can trust you LAN and have
an independent safe server with Postgres running you can connect the 3 tills on it, et voilà. As you mentionned there are cases when
this architecture might fail: if the DB servers or the network goes down. It's a trade off, if you think they are reliable enough
you can go this way. On the server side I think you should only fear hardware issues, Postgres is very reliable. Same for the
network, but it's not applicable for a WAN of course.
OOTB, in all cases you need ofbiz.jar. (see startofbizPos.bat)

From: "hzzg6y" <[email protected]>
Need your help on architecturing OFBIZ. I am on a VPS with CentOS 5.6 Linux.
I have taken Ofbiz 10.04 Zip & using PostgreSQL.
This VPS is my Central upstream main server having single Postgresql DB
server.
Now consider a case : I have Retail shop having 3 tills. Every till should
work even though the network is down so that they can indepenedently trade
Option 1 :I need to know whether I need to have three independent postgres
SQL DB on each till ? I feel yes, so that performance &
network down do not impact trade.
Option 2 : If We make any one main master Till having Postgres SQL DB ( or
inside Retail shop inside server ) & other tills are just acting as
Dummy tills emulated POS terminals then if master till ( Retail shop inside
server ) goes down, we cannot trade at all.
Option 3 : If the retail shop don't have Touch screens tills, can they use
the Webpos based on Retail shop inside server based locally.
Please can you explain me the difference between WEBPOS & POS instance on
Touch Screen.
Please advice how can I have just use Pos.jar ( light version if possible)
file instead of ofbiz.jar
