Total Information Quality and Data Quality?

Me and a friend are currently writing a short paper about Data Quality (problems, causes, solutions) at our university.

I read the article "Total Information Quality Management, a Complete Methodology for IQ Management" at

http://www.dmreview.com/article_sub.cfm?articleId=7320

This made me thinking about a very basic question. I know the difference between "Data" and "Information", but what is the difference between Data Quality and Information Quality (and further on "Total Information Quality Management" (TIQM) and "Total Data Quality Management" (TQDM), see the MIT Total Data Quality Program at http://web.mit.edu/tdqm)?

Can Information Quality and Data Quality be considered synonyms, because quality information always relies on quality data? The above article refers to "Data quality" and e.g. "Data cleaning software". I already searched Google, but despite hundreds of texts about the difference between data and information there were no information about a difference between Data Quality and Information Quality. Am I right with my assumption or am I totally wrong?

Thank you very much. Received on Sat May 22 2004 - 20:12:46 CEST
