EXPRESS-G Syntax Summary for Entities and Relationships only

Entities are represented usinga solid-line rectangle containingthe entity name

Subtype/supertype relationshipsare represented by thick lines.The subtype end of the relationshipis marked with an unfilled circle.The ‘1’ annotation indicates thatthe subtypes are mutually exclusive.

Relationships are represented by thin lines.Although relationships are bidirectional, onedirection is emphasized, and the ‘to’ end ofthis emphasized direction is marked withan unfilled circle.The role of the emphasized relationship iswritten next to the relationship line, and thecardinality of the relationship is recorded.In this case, on organisation employs a setof people, where the set is constrained tohave at least one member (an organizationmust employ at least one person) and thereis no upper bound on the number of employees.If no cardinality is specified, it is implicitly 1.
