It just depends on how much information there is (to go with this example)
about each vial, and how much varies. If the information about a vial includes
its location, its contents, its decay counter, its weight, and (say) its color, and
all of those could vary pretty dramatically, with several hundred different values
for each of those data items, then it wouldn't do you any good to store a sort
of generic vial and keep track only of the variations from the generic.
On the other hand, if there is a high degree of similarity in the data values
representing these vials, then aggregation could work. So let's say that of
these 6000 vials, there are really only four colors, and five contents, and all
have the same weight. Twenty 'prototype' vials could then be stored, and then
for each prototype a list of locations and decay counters (only) would need to
be stored. Twenty lists of 300, with half the data held constant in each list of
300, this beats 6000 lists of one, with all data varying at will, so to speak.
It's more or less what the database people are referring to when they speak of
data normalization (feel free to jump in to refine, you database people).
Only very good knowledge of the data can tell for sure if this will help or not.
