This makes perfect sense. However, at times, an application has to do
things both ways: use objects interactively with it's interface, loading
and using objects as needed; and generate summaries from information
contained in a series of objects. 

For the second case, I've been thinking over two solution; the first is
moving data to a summary store periodically, already summarized; the other
is providing a mapping to a RDBMS for just the data you need summarized
and moving data over it periodically too.

The second solution seems sane enough, since it permits different
summaries based on data, and the mapping part can be straighforward if you
don't want to map the whole world, too.

Take care,
