Book 2011 for many reasons, a database may not satisfy those integrity constraints, and for that reason it is said to be inconsistent. However, and most likely, a large portion of the database is still semantically correct, in a sense that has to be made precise. After having provided a formal characterizati

We take advantage of the general complexity analysis to both introduce cardinality-based and attribute-based repairs (cf. Sections 5.7 and 5.8, respectively), and investigate the corresponding complexity of CQA.

Montserrat Vilà,Emili García-Berthouarts by choosing certain predicates of a prescribed arity. The . of the database consists of this set of predicates, possibly ., which can be seen as names for the arguments of the predicates, together with an indication of the domains where the attributes can take their values. Having chosen the sc
