DefaultGenericDaoDbFacade<T, Guid> implements QosDao<T> {
Line 15:     private final QosType qosType;
Line 16:     RowMapper<T> mapper = createEntityRowMapper();
> the convention is having the mapper as a static member of this mapper, per 
1. +1 for Moti's initial comment. This abstract base class exists only for 
Mappers functionality sharing!
Having independent Mapper class will allow more flexibility (Mappers hierarchy 
is independent from the DAO one) and enable testing it independently (without 
accessing DB).
2. The member should be private.

Line 19:         super("qos");
Line 20:         this.qosType = qosType;

+1 For Moti.
A query cannot use more than 1 index for accessing a single table.
