My (amateur) take. CDB model (based on functions) has three advantages over RDB model (based on relations):
1. Easier modelling sum types (inheritance) due to duality.
2. Better handling of null due to labelled null.
3. Better foundation of elementary types (they're just another table ids). (Column stores often do that already, if your question is about storage.)
