We don't have any plans to do this: supporting databases is something that
we plan to expand on even further, with closer integration with Revolution
and an expanded feature set: it is a core part of the Revolution product.

Multiple (simultaneous) users. Keeping the data set valid is the tricky 
part. That's what a DBMS does for you.

Right now Valentina developers do next:

1) use trick open/close. In this way Valentina is able keep 20-30 users.

2) write own server part and client part and handle networking.
I have hear that MetaCard can allow build server in 5 minutes. So this
should not be show stopper for MC developers.

We are going start direct Server development in May.
And get first draft beta in 2-3 months.

How does Valentina currently run over a network, and with multiple users?
I know your working on this...but is there any way to do something like
this now?

Revolution supports MySQL, ODBC, and Oracle cross platform for this..but
you can't exactly distribute these database servers easily with your
application!

For a data set that small why not just use property arrays in a stackfile?

Are you building the client, the server or both? If only the client and
the server hosting the database also has a web server, then the client
can work together with a cgi script as discussed the other day on the
list which does the database work and answers back the result to the
client.

I used Valentina briefly (both mac and win) and was impressed with its
speed. Learning curve was kind of steep though.

Hi Leston,

Yes, Valentina is very MetaCard (and Revolution) friendly,

I should mention on Revolution site they have great examples of using
Valentina with Revolution.

As I understand, you need build APPLICATION with embedded db engine.
As mention not so far one developer, for MacOS is the only choice today for
standalone development.

I have been looking the paradigmasoft website for information about

Anyone on this list have any experience using their XCMD (on either/both

< 1 Mb of data
No control over how often it will be accessed, but based on the specialized 
nature of the program, demand for it won't be high. So I would say 
definitely on the "not very often" side of the scale.

Don't know. This program will be bundled with a textbook that is sold all

database and MC

[Leston Drake]

Hi all,

I'm working on a database application that requires
(1) cross platform Win/Mac (that's why I'm using MC!)
(2) runs over a network

Item 2 causes some issues for a database application.
Specifically, the issues of posting changes to the data
when multiple users are working with it (things that a
typical DBMS handles).

Does anyone know a cross-platform, MC-friendly solution?
I'm thinking there might be some 3rd party products that
could be used. Valentina? (I vaguely recall some discussion
about it on this list, not quite sure of its capabilities or MC
friendliness)

Thanks a bunch.
