Abstract:

In our increasingly interconnected and interdependent information society,
the Quality of Service (QoS) and Quality of Data (QoD) experienced by the
users determine the success or failure of any mission-critical,
data-driven application. In this talk, we illustrate the trade-offs
between QoS and QoD, and present algorithms to control this trade-off,
while providing quality guarantees to the users. We use three different
data management environments as our domain examples: (1) dynamic,
database-driven web sites, (2) sensor networks, and (3) mission-critical,
realtime database systems. We show that in all cases, users can benefit
greatly by controlling the trade-off between QoS and QoD. Finally, we
present Quality Contracts, a unifying framework for specifying user
preferences over QoS and QoD.
