8. EXPRESS-G Syntax Summary for Entities and Relationships only Entities are represented using a solid-line rectangle containing the entity name Subtype/supertype relationships are represented by thick lines. The subtype end of the relationship is marked with an unfilled circle. The ‘1’ annotation indicates that the subtypes are mutually exclusive. Relationships are represented by thin lines. Although relationships are bidirectional, one direction is emphasized, and the ‘to’ end of this emphasized direction is marked with an unfilled circle. The role of the emphasized relationship is written next to the relationship line, and the cardinality of the relationship is recorded. In this case, on organisation employs a set of people, where the set is constrained to have at least one member (an organization must employ at least one person) and there is no upper bound on the number of employees. If no cardinality is specified, it is implicitly 1. Organisation MaleFemale Person EMPLOYS S[1:?] 1
