Applying an update method to a set of receivers
Marc Andries, Luca Cabibbo, Jan Paredaens, Jan van den Bussche
Pages: 1-40
DOI: 10.1145/383734.383735
In the context of object databases, we study the application of an update method to a collection of receivers rather than to a single one. The obvious strategy of applying the update to the receivers one after the other, in some arbitrary...

Probabilistic temporal databases, I: algebra
Alex Dekhtyar, Robert Ross, V. S. Subrahmanian
Pages: 41-95
DOI: 10.1145/383734.383736
Dyreson and Snodgrass have drawn attention to the fact that, in many temporal database applications, there is often uncertainty about the start time of events, the end time of events, and the duration of events. When the granularity of time is...

I/O reference behavior of production database workloads and the TPC benchmarks—an analysis at the logical level
Windsor W. Hsu, Alan Jay Smith, Honesty C. Young
Pages: 96-143
DOI: 10.1145/383734.383737
As improvements in processor performance continue to far outpace improvements in storage performance, I/O is increasingly the bottleneck in computer systems, especially in large database systems that manage huge amoungs of data. The key to...
