/** 

Represents a DSC client interface to manipulate the DSC(Dynamic Start-up Configuration) database. A thread uses this class to

set up a connection with the DSC database. 

Is used to store DSC items that contain the information needed to launch After Market Application (AMA).

Multiple DSCs can be stored in the DSC database identified by different DSC IDs. A default DSC Uid, KDefaultSymbianDsc,

is provided.

All items within a DSC are unique. A duplicate item is defined as having the same filename and

arguments as another already in that particular DSC.

Uses transaction mechanism provided by the data source to ensure that DSC items will be added in a consistent manner 

to maintain data integrity. 

Requires PlatSec capabilities to add, delete DSC, and to read, add, update, or remove the items in a DSC.
