A DBMS Prototype to Support Extended NF2 Relations: An Integrated View on Flat Tables and Hierarchies

Summary: Prototype DBMS for extended NF2 relations, unifying flat tables, lists, and hierarchies. Presents a logical model, a query language, and storage alternatives to implement generalized relations, evaluating integrated architecture to overcome drawbacks of external extensions.
