[Zope] ZTables (Tablula) and SQL databases

[Robert OConnor]

Looking for some enlightenment:
<set learning on>

I understand that Ztables was formerly Tabula an
object database.  

If one were starting from scratch without legacy data
would it make sense to use an object database instead
of a relational database?  

If so, is ZTables/Tabula a full, robust database
system that can scale up and exceed the
features of Oracle or SQLxxx databases?

What are the pros/cons of Object vs
Relational databases.

Currently it appears that Ztables/Tabula
is priced at $1,500 but eventually may become
open source.

From recent posts on the list

*"Make site searchable"
*"one 'document' in many 'folders'"

It seems like Ztables would be an Ideal 
solution to these problems.  ie, rather
than the kludge of multiple copies
of the SAME document, ONE copy in
the database.  Also, searching by
key or full text would be possible.

But for further enlightenment, can anyone
point to good examples on the web of the 
use of ZTables/Tabula?

woops, your request to <set learning off>
has been denied!   :-)
