An algebraic approach to static analysis of active database rules
Elena Baralis, Jennifer Widom
Pages: 269-332
DOI: 10.1145/363951.363954
Rules in active database systems can be very difficult to program due to the unstructured and unpredictable nature of rule processing. We provide static analysis techniques for predicting whether a given rule set is guaranteed to terminate and...

A new approach to developing and implementing eager database replication protocols
Bettina Kemme, Gustavo Alonso
Pages: 333-379
DOI: 10.1145/363951.363955
Database replication is traditionally seen as a way to increase the availability and performance of distributed databases. Although a large number of protocols providing data consistency and fault-tolerance have been proposed, few of these ideas...

Theory of dependence values
Rosa Meo
Pages: 380-406
DOI: 10.1145/363951.363956
A new model to evaluate dependencies in data mining problems is presented and discussed. The well-known concept of the association rule is replaced by the new definition of dependence value, which is a single real number uniquely associated with...
