[EN] Inconsistency in large database systems is commonplace and therefore must be controlled in order to not get out of hand. Consistency in database systems is encoded by integrity constraints. Inconsistency thus corresponds ...

[EN] The lack of quality of stored data is reflected by violations of integrity constraints. Answers to queries in databases containing bad quality information usually cannot be trusted. Nevertheless, many answers given ...

[EN] The quality of the information provided by databases can be captured by integrity constraints. Thus, violated cases of constraints may serve as a basis for measuring the quality of given database states. A quality ...

Business rules enhance the integrity of information systems. However, their maintenance does not scale up easily to distributed systems with concurrent transactions. To a large extent, that is due to two problematic ...

[EN] A large diversity of different approaches to integrity checking has been proposed in the literature. We present a generic approach to integrity checking that is based on inconsistency metrics. It subsumes many known ...

Uncertainty and data integrity are closely related. The uncertainty of data can be modeled and maintained by existing database integrity technology. The usual requirement that integrity constraints must always be satisfied ...

[EN] In practice, knowledge-based reasoning for decision making must be inconsistency-tolerant since, for decision making, contradictory data are unavoidable. We present a measure-based concept of inconsistency-tolerant ...

Many distributed services need to be scalable: internet search, electronic commerce, e-government... In order to achieve scalability, high availability and fault tolerance, such applications rely on replicated components. ...
