<p>The <strong>dialect</strong> is the system SQLAlchemy uses to communicate with various types of <a class="reference internal" href="../glossary.html#term-dbapi"><span class="xref std std-term">DBAPI</span></a> implementations and databases.
The sections that follow contain reference documentation and notes specific to the usage of each backend, as well as notes
for the various DBAPIs.</p>
<p>All dialects require that an appropriate DBAPI driver is installed.</p>
