[REBOL] datebases

datebases

howdy guys,

ok, having items in a database, like:

number
title
summery
list (list-item 1, list-item 2,...)
price

would it be best to include all these fields per item, or have all of
each field grouped together? like:

;numbers: [1,2,1000]
;titles: [blah blah]

I wanna be able to use my little database as the basis for a shopping
cart, or to convert it to xml, but am not sure about how to handle
nested blocks.

thanks!
