Discussing the Open Data Platform and Apache Spark

Some latest news from vendors in the Hadoop and/or big data space

The second in a series of five articles about graph databases

This is part of the series about big data, discussing various issues, and their resolution, around Hadoop

Since some people seem to think that Hadoop equates to big data it is pertinent to discuss the former before talking about the latter.
