<h2>History</h2>
<p>MADlib grew out of discussions between database-engine developers, data
scientists, IT architects and academics, who were interested in new
approaches to scalable, sophisticated in-database analytics. These
discussions were written up in a paper in VLDB 2009 that coined the term
<a href="http://db.cs.berkeley.edu/papers/vldb09-madskills.pdf" target="blank">
"MAD Skills"</a> for data analysis. The MADlib software project began the
following year as a collaboration between researchers at
<a href="http://db.cs.berkeley.edu/" target="blank">UC Berkeley</a> and
engineers and data scientists at
<a href="http://www.greenplum.com/" target="blank">EMC/Greenplum.</a></p>
