[Zope] Request for comparison...

Oracle IFS stores stuff to an Oracle DB, that's what it was built for ;-)

Zope stores stuff where you tell it to store stuff. If you use the ZODB, it
stores to the ZODB (which can be a single file, or a BerkleyDB, or whatever
implementation of ZODB you are using), if you use it with SQL RDBMS, it
might store stuff there, and LocalFS or ExtFile store stuff to the file
system ... (It's that easy, or that complicated, as you like it)

I am not the expert on this, but AFAIK, Zope holds some index tables in
memory and loads objects into memory when needed, with some caching (e.g. an
"objectValues" call will load all the objects in a folderish object like
"Folder").

That's far from having the whole system in memory ;-)
