That's the thing that always gets me: The 'connections' cost.
One of the plus sides of Open Source is there are no connection costs
for your database, you decide on the limitations/access rights/
priviliges (delete where least confusing).
I'm not knocking commercial databases for charging for their product,
but I will for that very simple limitation (yes, I do see it as a
limitation).
It's especially limiting for those on a shoestring budget with great
ideas, and the commercial vendors lose out because of this: You have
this great idea for an app, you see great technology in a commercial
database, but you can't afford the unlimited connections licence.
Your product will not sell on the basis of 5 connections, so you look
around again and notice the Open Source alternatives. What to do...
What to do... You incorporate the Open Source database, commercial
vendor loses a potential client. Maybe, just maybe, in the future you
can then afford the commercial database: Do you switch to the
commercial/supported product? Do you risk changing the infrastructure
of your app?
Way I see it.
Cheers,
Luis.

Hi Stephen,
P.S. (sorry for kind of advertise, which I consider as information):
yes, I need to know this.
Ruslan, I've gone a long way into my project. I have questions:
1. Does Valentina run the main MySQL syntax as is, or is it very
different.
Valentina 2 supports STRICTLY SQL92 (we have use papers of ANSI)
+ we add some useful SQL extensions that can be found in mySQL
and other dbs. For example CREATE TABLE IF EXISTS
+ we have own unique Valentina extensions of SQL
http://www.valentina-db.com/dokuwiki/doku.php?
id=paradigma:public:en:documen
tation:vsql:reference:sqlgrammar
So answer yes, if you have write SQL which follow SQL92 then it
should be
easy.
The only feature of Relational model that we have not implement
so far -- ability to make Primary and Foreign Key on few fields.
Because I am sure this is bad idea do such keys in db structure.
We will add this soon. Just to be more compatible.
Valentina have like mySQL a rich set of functions, so here also all
right.
2. Is there a tool like CocoaMySQL (macintosh) to administer the
Valentina Database?
Valentina Studio.
3. You quoted a developer price for Valentina - $199 - is that for
one seat, deployed on any number of applications?
$199 - this is for ADK like Valentina for Revolution. Single Platform.
yes this is for developer seat.
this not include server.
--------
For Application developers that want distribute server we have
VDN - Valentina Developer Network.
Our license is very simple and flexible. :-)
Flexibility and many options sometimes confuse people.
Our license is made to satisfy even such $30 - app - developers.
VDN price $599
You pay this ONCE, and you get
* Valentina Embedded Server - 5 connection. Royalty free
- so you can sale even millions copies of your app with vserver
- you can develop any number of applications.
- you get during 2 or 4 years free updates of all new versions.
* Valentina for Revolution itself. As separate product its price $299.
* You get Valentina Office Server - 5 connections for MAC and for WIN.
for no-resale and use in your home/office on 2 computers (mac+win)
As separate product Valentina Office Server/5 has price $300.
So this is value $300 + $300 = $600
* also you get Valentina Studio ($60) GUI tool to manage database
as locally
so remotely.
* also you get batch of 10 connections for resale ($200).
----------------------------------------------------------------------
-
Total: for $600 VDN you get :
Valentina for Revolution 300
Vserver Office win/5 300
Vserver Office win/5 300
Valentina Studio 60
10 connection 200
------------------------------------
$1160
+ Valentina Embedded Server - royalty free - how to estimate
price? ;-)
+ 2-4 years free upgrade
+ FREE support
+ you can use with VServer Office or Vserver Embedded
ANY other Valentina Client for FREE
Valentina for RB, Director, PHP,
.NET, C/C++, Cocoa, COM, VB, Delphi,...
4. The cost of the Valentina server - per user?
* ZERO if you use royalty free Embedded Server with
5 simultaneous connections.
* any additional connection can be as low as $1-20
depending on option you choose.
