Re: suggested persistence approach for new app

Hi Charles,

Depending on your volumes, don't overlook the BOSS for a seamless approach
to avoid the impedance mis-match.

I once had a gig at the National Grid, and they wanted to use GemStone to
persist the model of the Grid. I initially did it "in memory", and as the
model was rebuilt every 15 minutes, we found it was enough.

Memory has come a long way since then, so this may be another approach
depending on your app?

Cheers,

Stewart
