solidDB

<h2 id="technology">Technology</h2>
<p>solidDB includes an <a href="/facts/In-memory_database/Am2VvJs4">in-memory database</a> as well as a traditional disk based <a href="/facts/Database/VYcpkevb">database</a>, which both employ the same <a href="/facts/SQL/UjQLJcYm">SQL</a> interface, and a <a href="/facts/High_availability/y3J8GnEo">high availability</a> option. Both in-memory and disk based engines coexist inside the same server process, and a single SQL statement can access data from both engines. The High Availability option maintains two copies of the data synchronized at all times. solidDB can be embedded directly into applications and run virtually unattended for lower total cost-of-ownership.
