Module documentation for 0.12.0
This library maps your datatypes to a relational model, in a way similar to what ORM libraries do in object-oriented programming. The mapping can be configured to work with almost any schema. Groundhog supports schema migrations, composite keys, advanced expressions in queries, and much more. See tutorial https://www.schoolofhaskell.com/user/lykahb/groundhog and examples https://github.com/lykahb/groundhog/tree/master/examples on GitHub.
