The database from which these statistics are drawn is primarily used to manage the DAF applications and payments (in real time) and so does not undergo any formal validation processes.
Defnyddir y gronfa ddata, y tynnir yr ystadegau hyn ohoni, yn bennaf i ymdrin â cheisiadau a thaliadau'r DAF (mewn amser real) ac felly ni chynhelir unrhyw brosesau dilysu ffurfiol.
