Actually it would be similar to a table in a RDBMS with the table being in
it's own file. As per a reply from Philip, it really isn't necessary for
this to be in it's own file. This doesn't really have anything to do with
transactions per se. Transactions are somewhat independent of this idea and
of storages. My idea had ZODB operating exactly as it currently does except
with multiple files based on classes because certain objects will have
different usage characteristics.

That said. I like better what Philip is proposing with Racks as it fully
satisfies my thoughts and provides an overall framework and philosophy for
development which much more versatile and extensable.

Hope this helps.
