The ZODB performs very well for such data text-oriented data, although 
more structured data is perhaps best held in an RDBMS. Zope has good 
RDBMS connectivity, so you have the choice to handle the data in the 
most appropriate way - but with the RDBMS as well as the ZODB rather 
than instead of.

I'd like to know if there is a one-size-fits-all answer to this question 
myself - I always call scripts from templates, but that has more to do 
with my own understanding of it than anything else.

The predominant mind-set in the Zope community seems to be that of a 
Python programmer, and from that perspective calling the template from 
the script makes sense. I am a refugee from ASP, so once I had been 
re-educated to stop trying to mix code and mark-up I found myself 
calling scripts from templates.
