Sorry for the delay in the answers, I've been out this week.
zetadb will help you if you want to use Zope with relational
databases. Basically, it will generate ZPT's and SQL Methods to do a
typicall maintaince of your relational tables. After that, you will be
able to modify the generated objects in order to add or change some
functionalities. It's a way to save some time writing boaring code.
To change some of generated objects, just follow the ZPT or SQL Methods
documentation.
As far as I know, zetadb has been used to develop small and medium
applications (until 10-12 tables, aprox). To develop big and complex
applications, we use Zope with ZODB, not relational databases.

Dear Juergen,
Thank you very much for answering my request. I'm definitely not looking at
enhancing ZetaDB, on the contrary, I'm trying to understand it.
I've already tested it and even managed to define macros and add some
functionality to the base objects created by ZetaDB from the mySQL database I
have.
The point is that I can't see what I can do with it (from where to where goes its functionality): There's no description of the
objects available (no sintaxe). It is mentioned in the available 7 page document that there are objects "db",
"table_name", "filds", "pk" ("record"???), but there's no clue on how to use them.
I also tried Zope website and Google search for any ZetaDB based projcts, but
found nothing.
I'm far from being an expert with Zope, but I know I can start with a tool and
make something usefull with it if I have the time and the documentation
available. In the case of ZetaDB, the documentation available is too scarce for
my level of knowledge with Zope. I will have to quit from using it.
If you take for example the generic ZPTs of Zope. You will find many
documentation and guides on it. Then it is said that ZetaDB extends the
functionality of ZPTs, but that's it, you are left on your own to go. OK, I
accept it, that's one the costs of some Open Source and/or Free tools: you get
what is offered and that's it.
Kind regards,
Lúcio
