What is the problem?
Amounts of complex data growing faster than capability to analyze it

but…
We are lost in this space
Data Information Knowledge

What did we learn?
Not enough to connect database to the Web Tools that fit the way we think and work
• Easier and faster data access• Better understanding of information space• Discover new relationships, anomalies
