Hello Johannes, no, sorry, HaskellDB is only meant for RDBM back ends, it eventually generates SQL (Strings). I tried to create an EDSL for relational algebra in the finally tagless style. This would theoretically allow to create entirely abstract expressions which could then be evaluated to either SQL or in-memory code or whatever. Of course I don't even know how to get started and at the moment it's on the very top of my wish-list because I really need it badly. All my code eventually turned into spaghetti code and without being able to express the algorithm abstractly(but correctly) and decide on implementation later I don't think will even try to untangle my mess, because at least it works.

Is there a haskelldb-driver that works with a datasource that is in memory, as a Haskell object? (like LINQ can work on C# collections) - J.
