Maintenance of implication integrity constraints under updates to constraints
Semantic integrity constraints are used for enforcing the integrity of the database as well as for improving the efficiency of the database utilization. Although semantic integrity constraints are usually much more static as compared to the data itself, ...
Nested Transactions with Integrity Constraints
Selected papers from the Eight International Workshop on Foundations of Models and Languages for Data and Objects, Transactions and Database DynamicsThis paper presents a solution to check integrity constraints in database systems supporting nested transactions. Using nested transactions allows to introduce parallelism inside a transaction and to partially recover failing transactions by defining a ...

TARK '88: Proceedings of the 2nd conference on Theoretical aspects of reasoning about knowledgeWe address the concept of a static integrity constraint as it arises in databases and Artificial Intelligence knowledge representation languages. Such constraints are meant to characterize the acceptable states of a knowledge base, and are used to ...
