Abstract

A merging technique for relational schemas consisting of relation-schemes, key dependencies, referential integrity constraints, and null constraints is presented. The author examines the conditions required for using this technique with relational database management systems that provide different mechanisms for maintaining null and referential integrity constraints. For relational schemas developed using an extended entity-relationship (EER) oriented design methodology, it is shown that a relation-scheme can be used for representing multiple object-sets not only for the standard binary many-to-one relationship-set structure, but for more complex structures as well. >
