<h2>Further Information</h2>
<p>SQLite is free and works great.
Most people use SQLite without
any kind of license or support.</p>
<p>Free support for SQLite is available on the public
<a href="https://sqlite.org/forum/forummain">SQLite Forum</a>.
The forum is monitored by a large
community of experts, including the core SQLite development team,
who are able to resolve just about
any problems with SQLite that you are likely to have.</p>
<p>If you do not want to discuss your issues on a public and open forum, an
<a href="https://www.hwaci.com/sw/sqlite/ams.html">Annual Maintenance
Subscription</a> or "AMS" might
serve your needs better.
An AMS entitles you to private email support directly from the developers of
SQLite. The level of support with an AMS is similar to the support one
gets from the public forum except that an AMS includes a unilateral
promise of non-disclosure, so with an AMS you can discuss your issues
with the SQLite developers in private, without the whole world watching.
An AMS costs $1500 per year.</p>
<p>Users with more advanced support needs can opt for a
<a href="https://www.hwaci.com/sw/sqlite/tech.html">Technical Support
Agreement</a>.
Technical support agreements are customized to the needs of each
individual client, but generally include direct telephone support
and priority handling of issues and bugs. Guaranteed response time
is available as an option. The cost of
technical support varies but is generally
in the range of $8000 to $35000 per year.</p>
<p>If SQLite is "mission critical" to your company, then you may
want to become an
<a href="https://www.hwaci.com/sw/sqlite/member.html">SQLite Consortium
Member</a>. The SQLite
Consortium is a collaboration of companies who sponsor ongoing development
of SQLite in exchange for enterprise-level technical support, on-site
visits from the SQLite developers, unlimited access to all licensed
products, and strong guarantees that SQLite will remain in the public
domain, free and independent, and will not come under the control of
a competitor.</p>
<a name="ext"></a>
<h2>Software Licenses</h2>
<p>The SQLite source code is in the
<a href="https://www.sqlite.org/copyright.html">public domain</a>,
and is free for use
by anyone and for any purpose. No license is required. However, some
users desire a license so that they can have warranty of title, or just
because their company lawyers say they need one. A
<a href="https://www.hwaci.com/cgi-bin/license-step1">perpetual license</a>
and warranty
of title for the core SQLite source code is available for this purpose.</p>
<p>The
<a href="https://www.hwaci.com/cgi-bin/see-step1">SQLite Encryption
Extension (SEE)</a>,
the <a href="https://www.hwaci.com/cgi-bin/zipvfs-step1">ZIPVFS Extension</a>,
and the <a href="https://www.hwaci.com/cgi-bin/scerod-step1">Compressed and
Encrypted ReadOnly Database (CEROD)</a> extension are enhanced versions
of SQLite that handle encrypted
and/or compressed databases. SEE can read and write encrypted databases.
SEE encrypts all database content, including metadata, so that the database
file appears as white noise. ZIPVFS
compresses the database on-the-fly using application-supplied
compression and decompression functions.
CEROD reads a compressed database that is
also optionally encrypted. All of SEE, ZIPVFS, and CEROD are
supplied in source code form only; the licensee is responsible for
compiling the products for their chosen platform. It is not difficult
to compile any of these extension. All products come in the form of an
<a href="https://www.sqlite.org/amalgamation.html">amalgamated source file</a>
named "sqlite3.c". So compiling SEE, ZIPVFS, or CEROD into an application
is simply a matter of substituting the SEE-, ZIPVFS-, or CEROD-enabled sqlite3.c
source file in place of the public-domain sqlite3.c source file and recompiling.
Licenses for SEE, ZIPVFS, and CEROD are perpetual.
All three extension can read and write ordinary,
uncompressed and unencrypted database files.</p>
<a name="th3"></a>
<h2>Testing Services</h2>
<p>The <a href="https://www.sqlite.org/th3.html">Test Harness #3 (TH3)</a> is
a suite of test cases for SQLite that provide 100% branch test coverage
(and 100% modified condition/decision coverage) for the core SQLite in
an as-deployed configuration using only published and documented interfaces.
TH3 is designed for use with embedded devices, and is compatible with
DO-178B. Every release of the public-domain SQLite is tested using TH3,
and so all users benefit from the TH3 tests. But the TH3 tests are not
themselves public. Hardware or system manufactures who want to have
TH3 test run on their systems can negotiate a service agreement to have
the SQLite Developers run those tests.</p>
<h2>About The SQLite Team</h2>
<p>Paid support options and products are provided by
Hipp, Wyrick &amp; Company, Inc., (Hwaci), a
<a href="http://en.wikipedia.org/wiki/Georgia_(U.S._state)">Georgia</a>
corporation
with headquarters in
<a href="http://en.wikipedia.org/wiki/Charlotte,_North_Carolina">
Charlotte, North Carolina</a> and has been in business since
1992.
Hwaci has an international team of
employees and associates representing the best available talent.
We are a 100% engineering company. There is
no sales staff.
Our goal is to provide outstanding service and honest advice
without spin or sales-talk.</p>
<p>Hwaci is a small company but it is
also closely held and debt-free and has low
fixed costs, which means that it is largely immune to buy-outs,
take-overs, and market down-turns. Hwaci intends to
continue operating in its current form, and at roughly its current
size until at least the year 2050.
We expect to be here when you need us,
even if that need is many years in the future.</p>
