Abstract: This talk presents the design of a novel distributed database system that was designed to give query response time guarantees, independent of the query and update workload. The system makes use of aggressive sharing of operations (e.g., scans and joins) between concurrent queries and updates. Specifically, this talk gives details of the storage manager (called Crescando) and of the query

processor (called SharedDB), both of which can be deployed in a distributed and scalable infrastructure. Furthermore, the talk presents the results of performance experiments with workloads from an airline reservation system.
