<h3>What Is SQLite?</h3>
<p>SQLite is a C-language library that implements a
<a href="footprint.html">small</a>,
<a href="fasterthanfs.html">fast</a>,
<a href="selfcontained.html">self-contained</a>,
<a href="hirely.html">high-reliability</a>,
<a href="fullsql.html">full-featured</a>,
SQL database engine.
SQLite is the <a href="mostdeployed.html">most used</a> database engine in the world.
SQLite is built into all mobile phones and most computers and
comes bundled inside countless other applications that people
use every day.
<a href="about.html">More Information...</a>
<p>
The SQLite <a href="fileformat2.html">file format</a> is stable, cross-platform, and
backwards compatible and the developers pledge to keep it
that way <a href="lts.html">through the year 2050</a>. SQLite database
files are commonly used as containers to transfer rich
content between systems
<a href="aff_short.html">[1]</a>
<a href="sqlar.html">[2]</a>
<a href="appfileformat.html">[3]</a>
and as a long-term archival format
for data
<a href="locrsf.html">[4]</a>.
There are over 1 trillion (1e12)
SQLite databases in active use
<a href="mostdeployed.html">[5]</a>.
<p>
SQLite <a href="https://sqlite.org/src">source code</a>
is in the <a href="copyright.html">public-domain</a> and is free to
everyone to use for any purpose.
