Minimal-Change Integrity Maintenance Using Tuple Deletions
We address the problem of minimal-change integrity maintenance in the context of integrity constraints in relational databases. We assume that integrity-restoration actions are limited to tuple deletions. We identify two basic computational issues: repair checking (is a database instance a repair of a given database?) and consistent query answers [ABC99] (is a tuple an answer to a given query i...
متن کاملOn the Computational Complexity of Minimal-Change Integrity Maintenance in Relational Databases
We address the problem of minimal-change integrity maintenance in the context of integrity constraints in relational databases. Using the framework proposed by Arenas, Bertossi, and Chomicki [4], we focus on two basic computational issues: repair checking (is a database instance a repair of a given database?) and consistent query answers (is a tuple an answer to a given query in every repair of...
متن کاملOptimization Using Tuple Subsumption
A tuple t1 of relation R subsumes tuple t2 of R, with respect to a query Q if for every database, tuple t1 derives all, and possibly more, answers to query Q than derived by tuple t2. Therefore, the subsumed tuple t2 can be ignored with respect to Q in the presence of tuple t1 in relation R. This property nds use in a large number of problems. For instance: during query optimization subsumed tu...
متن کاملMaintenance Cost Analysis for Replacement Model with Perfect Minimal Repair
With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...
متن کاملIntegrity Maintenance in Extensible Databases
INTRODUCTION The use of databases for advanced applications is a rapidly growing and changing field, due to the continuous incorporation of new technologies and media in current systems. Whereas in the near past Database Management Systems (DBMS) mainly use to store and manage tabular data, now they need t model complex structured objects, multimedia data, semi-structured and unstructured docum...
