I am not sure I agree with,
"Data auditing is the process of doing a profile check and assessing the quality of data, to find how accurate it is. This can be achieved by keeping track of all the data changes."
A couple of points:
- you can't always know that data is correct. If the data is based on mathematical formula, and you have the inputs, you can. But you can't tell that my mobile telephone number is correct, or my date of birth. At least not without external validation. Quality is abstract.
- auditing goes beyond changing data. Tracking the viewing of data, or the printing of data, is very important. Examples can include celebrities who are hospitalized - you want to know if 300 hospital workers are viewing the patients chart (and shouldn't be).
I like this definition better: "[a] systematic examination of information use, resources and flows, with a verification by reference to both people and existing documents, in order to establish the extent to which they are contributing to an organisation’s objectives"
But interesting article.
