Zusammenfassung

The construction of a declarative query engine for a DBMS includes the challenge of compiling algebraic queries into efficient execution plans that can be run on top of the persistent storage. This work pursues the goal of employing foldr-build deforestation for the derivation of efficient streaming programs - programs that do not allocate intermediate data structures to perform their task - from algebraic (combinator) query plans. The query engine is based on the insertion representation of collections and base types, making the deforestation idea amenable to a wide range of type constructors and operators. In addition to the removal of intermediate data structures, deforestation actually implements certain algebraic optimizations for free. Query deforestation is a generally applicable technique that puts the derivation of streaming programs in a compact formal framework that should be immediately applicable.
