/**
 * <p>Title: </p>
 * <p>Description:  Stateless Session Bean for accessing cardholder personal information (CPI) data.
 *                  This class acts like a facade, and all of the CPI data access activities
 *                  must go through this session facade. It will first perform security check
 *                  to see if the user has permission to do the requested works.
 *                  If the security check fails, it will throw BusinessException to the caller.
 *                  If the security check succeeds, it will then dispatch the data access
 *                  request to the corresponding DAO/entity beans to do the concrete works.
 *
 *                  This class is also the place to audit all of the eBank activities</p>
