| <h2 id="About">About</h2> |
| <p>Apache Trafodion is a webscale SQL-on-Hadoop solution enabling transactional or operational workloads on Apache Hadoop. </p> |
| <p>The name "Trafodion" (the Welsh word for transactions, pronounced "Tra-vod-eee-on") was chosen specifically to emphasize the differentiation that Trafodion provides in closing a critical gap in the Hadoop ecosystem. </p> |
| <p>Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data applications to run on Hadoop. </p> |

| <blockquote><a href="http://trafodion.apache.org/">Apache Trafodion</a> is a webscale SQL-on-Hadoop solution enabling transactional or operational |
| workloads on Hadoop. <br /><br />The name "Trafodion" (the Welsh word for transactions, pronounced |
| "Tra-vod-eee-on") was chosen specifically to emphasize the differentiation that |
| Trafodion provides in closing a critical gap in the Hadoop ecosystem.<br /><br /> |
| Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends |
| Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data |
| applications to run on Hadoop.</blockquote> |
