FunQuery

A custom language that allows for the definition of a data model and for writing functional queries on this model.
The data model combines parts of the relational data model (entities, relationships, keys) and abstract data types known from functional languages (sum, product, wrapper types).

The language comes with a code generator that can generate from the functional queries the data access layer of backend applications relying on relational databases as storage. The first supported generation target is Java with a jOOQ or QueryDSL.
