.... of (bonus 2000) and (salary bonus 2500) implies (salary 4500) while there is an integrity constraint (salary 5000) 2 Note that similar algorithms are also available for checking consistency of check constraints consisting of conjunctive predicates based on character string variables [68]. The above example shows the aspect of consistency for a set of row constraints. Consistency issues are also of concern for inter table constraints. Example 8. Consider the following set of integrity constraints, consisting of one row constraint and two inter table constraints, one requiring ....

....on integrity enforcement by triggers. A general overview of semantic integrity constraints in distributed and or federated databases is given in [55, 45, 69] The connection between integrity constraints and object objected database concepts such as subtyping and subclasses is discussed in [25, 4, 68]. The latter work particularly deals with the inheritance of integrity constraints and shows that there are integrity constraints that cannot be inherited to subclasses. Further interesting work on integrity constraints in object oriented databases can be found in [6, 43, 72] We have not ....
