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.
