            Abstract : 
The issues addressed include using a database query to discover a new rule, using not only positive examples (answer to a query) but also negative examples to discover new rules, and harmonizing a new rule and previous rules to remove inconsistencies. The main contribution is the development of a new tool for characterizing the exceptions in databases and evolving knowledge as a database evolves
