Data Curation, Analytics Collaboration Top Big Data Concerns

IT and data professionals are under increased pressure to deliver the goods when it comes to data – that is, insights that can help drive business decisions and boost profits. Toward that goal, many organizations are focusing on collaborative analytics to empower analysts and business users to get their jobs done with greater accuracy and speed.

Stephanie McReynolds, vice president at Alation, spoke with Information Management about what these trends mean, and her observations on the top data analytics and data management themes to emerge from the recent Strata & Hadoop World event in San Jose.
