Your link includes ODBC which in theory 4D supports directly and
should require little or no development on your part. In practice, I
have not had much luck with ODBC and third party data extraction tools
that support it. I have not tested version 13 or 14, but version 12
and prior crashed or simply did not work when trying to pull data from
4D. But it would be worth trying Winward with 4D via ODBC before
jumping into any of the more complicated options.

If I wanted to use 4D as a backend I get the impression I would need
to buy
a SQL Server license and then clients could connect to it via SQL.
Windward
mentions several flavors of SQL including:
- Microsoft SQL
- Oracle SQL
- MySQL
- PostgreSQL
Is it possible one of the tools for these would work with 4D?

Yeah - It's always helpful to have a pretty smart guy on the other end!

Dave,
I think you misunderstand 4D's SQL implementation. The only way to
connect to it from an outside application is via ODBC. Your first
paragraph below is correct -- you only need to active 4D's SQL Server
and see if the external app can work with it. But the external app
will be connecting to 4D via ODBC. I think this is what you are
looking for:

know there are options - and thats what
I'll let them know. We have a Team Developer database sandbox, and the
easiest thing for starters will be to turn on the SQL Server and see
what
happens (Lee - I don't think I'll need another SQL System.., at least I
hope not). I think you get a couple of connection licenses with Team
Developer. ?If it works well, then we can splurge on the full SQL
License
for the production machine which runs about $2000.
We will be on v14 in a couple of months and I can start playing with
the
JASON stuff.
As far as ODBC, it sounds nice, but the 4D Website is not very clear
on how
one would connect to 4D via ODBC. They mention 4D ODBC Pro expansion
for
connecting to an outside ODBC Source, but nothing about how external
databases would connect with 4D - in particular, what plugins and
licensing
your need.

Dave,
This is not very difficult.
Just install the ODBC driver on the client side, setup the ODBC source ?
and have the external app use that source.
The 4D ODBC driver is part of the full 4D download. The manual in pdf ?
format is included.
You will have to start the SQL server on your 4D server, because ODBC ?
is connecting to the SQL server.
Keep in mind active SQL connections (in this case the ODBC flavor) are ?
eating up a client license. Which you can 'prevent' by buying and ?
installing the unlimited SQL server license.
So, you can test with your current 4D server license.
I haven't done this my self, but a customers IT guy is connecting to ?
our 4D server for reporting purposes. I just sent him the 4D ODBC ?
driver installer and his credentials and he did it all by himself. He ?
is probably a smart guy, but I'm sure the installation setup is pretty ?
straightforward.

If external app = non-4D app then everything below is true. ¬=A0Others
have already mentioned how this can be done 4D-to-4D via "direct
connection":
http://kb.4d.com/assetid=76310
Regarding licensing, details are here:
http://www.4d.com/products/4dv14/deployment.html
In particular the "Deployment feature" is "SQL Server".
