Powerful solutions enabling interoperability must allow applications to evolve and requirements of shared databases to change, while minimizing such changes on other integrated applications. Several approaches, such as the transparent schema evolution system (TSE) by Ra et al., schema versions by Lautemann, and integrated views by Bertino, have been(More)
The choices for mining of decentralized data are numerous, and we have developed techniques to enumerate and optimize decentralized frequent itemset counting. In this paper, we introduce our heuristic approach to improve the performance of such techniques developed in ways similar to query processing in database systems. We also describe empirical results(More)
