An increasing number of online applications operate ondata from disparate, and often wide-spread, data sources.This paper studies the design of a system for the automatedmonitoring of on-line data sources. In this system a numberof ad-hoc data warehouses, which maintain client-specifiedviews, are interposed between clients and data sources. Wepresent a model of coherence, referred to here as slackercoherence, to address the freshness problem in the context of pull-based protocols. We experimentally examinevarious techniques for estimating update rates and pollingadaptively. We also look at the impact on the coherencemodel performance of the request scheduling algorithm atthe source.
