An entity-relationship programming language

The syntax for an integrated E-R programming language is presented. The problems that arise when a query language is embedded in a general-purpose programming language are discussed. Other E-R languages are also discussed. The requirements for the language and a syntax for an E-R model in which entity sets are mutually disjoint and each entity type has a unique, perhaps multiattribute, key are presented. The syntax for a more limited model restricted to binary relationships between entity types and without attributes is presented. Some implementation considerations are discussed.<
