Uniform comparison of data models using containment modeling E. James Whitehead Jr.   View Paper (PDF)   Return to Hypermedia Systems and Data Models Abstract Containment data models are a subset of entity relationship models in which the allowed relationships are either a type of containment, storage, or inheritance. This paper describes containment relationships, and containment data models, applying them to model a broad range of monolithic, link server, and hyperbase systems, as well as the Dexter reference model, and the WWW with WebDAV extensions. A key quality of containment data models is their ability to model systems uniformly, allowing a broad range of systems to be compared consistently. DiSC'03 © 2003 Association for Computing Machinery
