Data quality focuses on
the attributes of data (e.g., accuracy, consistency, completeness)
and its suitability for meeting business requirements. But
this is the IT definition. A business definition orientates
toward the believability of the data. That is, how is the
data regarded to being true, real and credible. It's based on
perception and if people don't believe data (and it's host
application), they are not likely to use it. It could be of
high 'IT' quality and still not believed and then not used.
So, how do we increase the business believability of the
data. PPDM is posed to help out greatly this because key
pointers like source, row quality and effective/expiry dates are
modeled into every table.
