The graph-relational database, defined

The graph-relational database model is an extension of the relational paradigm that represents data as strongly typed objects containing set-valued scalar properties and links to other objects. Unlike traditional relational databases, graph-relational databases assign a unique identity to each object, allowing for connections between objects through links. Additionally, attributes in this model have cardinality, specifying the number of values that can be assigned to them. The graph-relational model also treats everything as a set with known type and cardinality, enabling set-theoretic operations like union. This new database abstraction is considered a spiritual successor to the relational paradigm and offers an alternative approach for data representation and management.
