Big three relational database vendors diverge on Hadoop
The three leaders of the relational database market are responding to the sudden mania for the data processing technology Hadoop in three very different ways.
While startups and established data warehousing vendors such as Sybase and Teradata are embracing Hadoop and its Google-developed progenitor, MapReduce, Microsoft is resisting it.
"We'd never bring Hadoop code into one of our products," said Microsoft technical fellow and University of Wisconsin-Madison professor David J. DeWitt. DeWitt's lack of interest is not surprising. DeWitt is an academic expert in parallel SQL databases, having co-invented three of them. He co-authored a paper this spring that argued that SQL databases still beat MapReduce at most tasks. He hasn't changed his mind.
