Big Data = Big opportunity (well for the marketing guys and their budgets anyway)
I have spent more time on Big Data this year than any other subject. Last week was Big Data week in London with Oracle's Big Data and Extreme Analytics summit  at which I was privileged  enough to speak at alongside Andy Mendelsohn, Senior VP, Database Server Technologies at Oracle and Doug Cutting, Chief Architect at Cloudera, and of course the person who created Hadoop. There are two big issues that i think we still need to crack in Big Data - demonstrable Return On Investment (ROI) that can be put as a cash quantity, and how do we ensure the provenance of the data analysed? That looks like my work for the next year.
