Database.DSH.Compiler

DSH compiler module exposes the function fromQ that can be used to execute DSH programs on a database. It transform the DSH program into FerryCore which is then translated into SQL (through a table algebra). The SQL code is executed on the database and then processed to form a Haskell value.
