Template Dependencies
Fereidoon Sadri, Jeffrey David Ullman · Journal of the ACM · 1982
Relauonal database theory has d~scovered complete axlomauzations for functional and multivalued dependencies.However, a database design system based on dependencies must deal with some more general kinds of dependencies than these--at least with embedded multivalued dependencies Yet no axiomatizatton for embedded multivalued dependencies is known.A more general class of dependencies, called "template dependencies," is detrmed in this paper, and a complete ax~omatizat~on is given for them.
