Abstract In many scenarios, a database instance violates a given set of integrity constraints. In such cases, it is often required to repair the database, that is, to restore its c...
A reparable database management system has the ability to automatically undo the set of transactions that are corrupted by a human error or malicious attack. The key technical chal...
For several reasons a database may not satisfy certain integrity constraints (ICs), for example, when it is the result of integrating several independent data sources. However, mo...
The objective of this paper is to investigate the problems related to the extensional integration of information sources. In particular, we propose an approach for managing incons...
Although conventional database management systems are designed to tolerate hardware and to a lesser extent even software errors, they cannot protect themselves against syntactical...
