N2 - Analytical query processing over complex objects often suffers from disappointing performance due to excessive use of nested-loop (element at a time) evaluation. Storing the data in a flattened form enables collection based processing (set at a time), gaining performance at the cost of having to write more complicated queries. This report proposes Dodo, an approach to automatic translation of queries from the complex objects domain into set-at-a-time operations against data stored in a flattened form.
