[Zope] Where is the code?

[Red Pineseed]

Thanks Rik,

You answered my question perfectly. This was my guess and
found the Data.fs. This makes me wonder though how the
implementation of the three tier separation, ie
data/logic/presentation is achieved. Do you have any idea?
What is the advantage of putting everything in a db?
Apparently if the db down, we will lose everything and
recovering from a db is pain as you may already know. Even
though it is great performance improvement to load the db in
RAM at run time, do you know of an other benefits?
