Each item represents a AMC (After Market Component) to be launched at phone boot time. </p> <p>A DSC API client, <xref href="GUID-EB3CA81E-8684-3851-A556-1C91CAD3891F.dita"><apiname>RDscStore</apiname></xref> requires connection to a DSC database before issuing any requests concerning a DSC. A client opens a connection to the underlying database server using this API. Each DSC is identified by a UID. One DSC has a default UID (<codeph>KDefaultSymbianDsc</codeph>) provided by Symbian. By default, this DSC is executed at the end of the startup procedure. The purpose of the default DSC is to allow generic AMCs. </p> <p>Though all of the insertion points for DSCs (and therefore their UIDs) are fixed when the ROM is built, DSCs themselves may be created and deleted at run time. Items may be added, removed, updated and retrieved using the functions supported by <xref href="GUID-EB3CA81E-8684-3851-A556-1C91CAD3891F.dita"><apiname>RDscStore</apiname></xref>.
