Incorporating Hierarchy in a Relational Model of Data
Summary: Extends the relational model to allow classes as attribute values, enabling object hierarchies. Supports inheritance, including multiple inheritance with exceptions, with class and instance facts treated as first-class, upward-compatible with the standard relational model.
