Is better that what you think, is easy and fast for example to add 500.000
objects to an ST OrderedCollection, and query them (if are not used, are paged
to disk). You can use also more machines, or a OODBMS.
Is like saying "how do you make linux scale if you can have sooo many files" :)

There are some systems like "cvs" for ST, but are frequently not used, because
the ST teams are small (coz more productive) in general, working with XP
practices (XP origin was in ST, same design patterns) and with frequents
What do you mean with "data formats"?
Also, in ST you read the 80% of the time, and type the 20%, is possible to know
the whole system, and one of the XP practice is the work rotation.

If you give the production system to someone, you can lock it :) Its similar
to giving the source.
