Abstract :
We try to describe synthetically the main problems which arise in the design of parallel relational database systems. Due to the breadth and the depth of the topic, it is obviously very hard to capture all relevant issues. The issues that are tackled include data placement, static and dynamic query optimization, resource allocation, statistics extraction, and cost estimation
