After one day at NoSQL East, I believe I can do a quick compare & contrast with OpenWorld.

nosql east 150x142 NoSQL East vs Oracle OpenWorld

oracleopenworld 150x150 NoSQL East vs Oracle OpenWorld

Cost To Go $600 $2500
Location Atlanta GA San Francisco CA
Number of Attendees 125 40,000
Laptop % in use during talks ~95% ~10%
Typical dress T-shirt & jeans Business Casual/Suits & no ties
General Content Much more technical Much more marketing/sales

None of this should be construed as a slam on either conference; they are each focused on different demographics.
