[ZODB-Dev] ZODB Intro

[Harm Kirchhoff]

I read the last two, I did not read the first one. That one is actually 
very good, but I think that the articles aim too high.

I am aiming even deeper: ZODB is good and easy to use and anyone who 
starts Python with the intention of using a database should consider 
ZODB and in order to do so, it's simplicity needs to be brought home 
even easier. What I am missing in those articles are practical issues 
for beginners:
What happens if my DB corrupts, if I loose my files ?
Can I use pprint to see the contents of my DB ?
How can I undo transactions, how can I pack ? How can I see the undolog 
and how can I set the variables for the undolog.
and so on.
