DATA PROCESSING SYSTEM AND METHOD FOR MAINTAINING CARDINALITY IN A RELATIONAL DATABASE

A relationships processing computing system provides for the recording and extraction of data objects (entities) and for development data representing a queried relationship between data objects (entities). The set of entities and relationships may be expanded at any time during the life of the system without reprogramming or compiling computer code and without disrupting concurrent use of the system. Complex inquiries, normally requiring multiple nested queries, may be performed without code level programming.
