[Newbies] How would I save an object to disk separately and load it when needed?

[Frank Church]

I am practicing the seaside.gemstone.com tutorial and I want to know
how to save just the object definitions and their data to a seperate
file, then load it again, or even into a different image and run the
website again.

It sounds like very newbie question, but I would be very much obliged.
