+<h2>SQLite is Transactional</h2>
+
+<p>A transactional database is one in which all changes and queries
+appear to be
+Atomic, Consistent, Isolated, and Durable
+(<a href="http://en.wikipedia.org/wiki/ACID">ACID</a>).
+SQLite implements
+<a href="http://en.wikipedia.org/wiki/Serializability">serializable</a>
+transactions that are atomic, consistent, isolated, and durable,
+even if the transaction is interrupted by a program crash, an
+operating system crash, or a power failure to the computer.
+</p>
+
+<p>
+We here restate and amplify the previous sentence for emphasis:
+All changes within a single transaction in SQLite either occur
+completely or not at all, even if the act of writing the change
+out to the disk is interrupted by
+<ul>
+<li>a program crash,</li>
+<li>an operating system crash, or</li>
+<li>a power failure.</li>
+</ul>
+<p>
+
+<p>
+The claim of the previous paragraph is extensively checked in the
+SQLite regression test suite using a special test harness that
+simulates the effects on a database file of operating system crashes
+and power failures.
