<context><p>The Comms Database has a set of parameters used
to configure communications on Symbian OS. The information stored in the Comms
Database is used to configure components in the comms stack. Information such
as connection preferences, account settings and some of the linkage between
components can be set in the comms stack. The configuration data is stored
in records in database tables. The data also has data schema to define the
tables. For more information and a full list of the settings in the Comms Database,
see the <xref href="GUID-58089281-9DD0-502D-8DFD-831E7BAA931E.dita">Reference</xref></p><p>The
Comms Database is configured in one of the following ways: </p> <ul>
<li id="GUID-3CFE8D23-F087-54D1-A6F3-83EDD0510609"><p>It is compiled from
a definition file into a binary file to ship in the ROM of a device. For more
information about how to compile the default version of the database see <xref href="GUID-00696F18-F1C8-5810-A9F9-E7215CA451A4.dita">Configuring comms database
using CED and CEDDUMP</xref>. </p> </li>
<li id="GUID-9FACDEE5-5DD7-5118-9C50-84857A379083"><p>It is modified from
the original ROM version via runtime changes made through the Comms Database
(CommsDat) API. For more information about the CommsDat API, see the <xref href="GUID-A19A1F43-E42B-5FC2-AE58-A7BC67B6733A.dita">Migrating from CommDb to
