management systems are mapped to the concepts and properties of an
either generic or preferably a domain specific ontology. This mapping
allows abstracting from data management specific characteristics like
normalization in relational database management systems. The mapping
also has another advantage. As on the other hand data mining
techniques are used to acquire the data's characteristics to decide

used perform optimal.
Data quality management analyses the data continually to find data of
