Cheep ORM is a simple reflection-based object relational mapping. It does not attempt to solve the Object-Relational mapping impedance mismatch, but opts for the "Acceptance of ORM limitations" solution.
It is best described as an Object-Row mapping - using reflection and JPA to perform CRUD operations on database rows, with some sugar for listing and iterating result sets.
