Thanks Greg, both references are very interesting. If I understand correctly, the DSH approach is to convert Haskell programs into SQL and run them inside the database. This seems a good solution when the program objective is to change data in the database according to some business logic or

Sorry for the awful message format in the first try! I am studying Haskell database libraries. In particular I am looking at haskelldb and the Takusen Database.Enumerator library. In haskelldb, there are very good ideas aiming to represent database objects as (typeable) Haskell objects, instead

Hi Tobias, Have you seen DSH [1]? You might also be interested in Persistent [2], but it sounds like it has different goals than what you are after. [1] http://hackage.haskell.org/package/DSH [2] http://www.yesodweb.com/book/persistent ___ Haskell-Cafe

I am studying Haskell database libraries. In particular I am looking at haskelldb and the Takusen Database.Enumerator library. In haskelldb, there are very good ideas aiming to represent database objects as (typeable) Haskell objects, instead of embedding SQL in plain strings. This is really an
