Well, the requirement is: keep a lot of data stored, don't loose any
of it, and you will not know what you will have to store (changing
number of fields and of different types)
But it is not all that bad, the fields will be integers, or text, or
floatingpoint numbers.
One option is, put it in a db as a huge text (or in textfiles, one
per object) and parse it when you need it. That might also work.
Why are you demanding sanity? I need crazy ideas to get this to work ;-)
