James and Pierre have given talks on the Pixie and Vx tools which Fotango
use to store data:

I like the idea of this:

These guys are a little evangelical but I find the idea intriguing.
I'm still not too sure how easy it would be to remember to have the
data migrate itself when you change your classes.  I think you'd need
some fairly rigorous run-time consistency checks.

Has anything like this been done in perl?  There is a ruby
implementation of this, so it can't be that hard :).

Both Pixie and Tangram are based on this principle; Tangram calls it
`orthogonal' storage of data; in essence, it's not interfering with
the damned objects just for your persistence mechanism.

For most applications, Pixie will be faster and more convenient, but
for some types of data access (eg, OLTP) it really reduces the number
of times that you have to hit the disk if you know your record size up
front - in which case a system like Tangram where you have to
explicitly tell the tool what columns you've got, and how big they are
is better.

It also spreads quite nicely and tastes yummy on a biscuit!

James Keller and Sons are reportedly in a bidding war with
Larry Ellison to acquire the rights to the recipe.

I thought that was last week?

I agree, this RDBMS stuff is old hat. I store my (arbitrary) data in a
BSD mailbox folder and interface through mutt's powerful limit (l) and
order (o) functions via the DBD::mutt layer which uses Term::Readline
 screen(1).

Oh! Don't tell me!
And when it's offline, that trans-dimensional-organic-memory
