Abstract

An easy-to-use, interactive facility for defining schemas for a mainframe database system has been developed that is more convenient than a linear language. The facility called Dbdefs, has several features that make it easy to use. It provides similar interfaces for defining schemas for two data models, relational and entity-relationship. An overview of Dbdefs is followed by discussion of the relational and entity-relationship interfaces.
