<p class="big">MADlib is an open-source library for scalable in-database
analytics. It provides data-parallel implementations of mathematical,
statistical and machine learning methods for structured and unstructured
data.</p>
<p class="big">The MADlib mission: to foster widespread development of
scalable analytic skills, by harnessing efforts from commercial practice,
academic research, and open-source development.</p>
<h2>Status</h2>
<p>The initial beta of MADlib is currently under active development. Although
the bulk of the code is standard SQL, some methods use platform-specific
subroutines to achieve good performance. Initial targets are PostgreSQL and
Greenplum; ports to other SQL platforms are expected. After the beta release,
we will invite participation from the broader community through a standard
open-source contribution submission process.</p>
<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 phrase
<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>
