<h1>What is NoSQL?</h1>
<h2>A Philosophical Movement</h2>
<ul>
<li>Freedom from the limitations and complexities of the relational model</li>
<li>Freedom from the licensing fees and incompatibilities of Oracle/Sybase/IBM/Microsoft/etc.</li>
<li>Freedom from the up-front design costs of schema-based data storage</li>
</ul>
<h2>A Technical Anti-Specification</h2>
<ul>
<li>No Structured Query Language</li>
<li>No fixed schemas</li>
<li>No joins (some may dispute this point)</li>
</ul>
<h2>A New Hope</h2>
<ul>
<li>True Horizontal Scalability</li>
<li>Excellent performance with large datasets and binary data</li>
<li>A safe haven for the lazy, the impatient, and the hubristic</li>
</ul>
<h2>The Phantom Menace</h2>
<ul>
<li>Not what everyone uses, for better or worse, 95% of the time</li>
<li>No standards</li>
<li>Weakened integrity assurances</li>
</ul>
