Thank you for your answer. I thought about exactly this definition a few days ago... this means that in some way all these papers, books and websites which define multiple dimensions of "data quality" are not really precise? That is, all other dimentions except accuracy should be mentioned with information quality and not with data quality?

One can find dimensions like completeness, timeliness etc. in conjunction with data quality definitions very often. I'm a little bit confused now whether your (and my) thoughts about this difference are correct or totally wrong because so many sources mention all these quality dimensions when talking about "data" quality.
