Quizplus · Accepted Answer

Relationships between tables are expressed through the use of foreign keys, which are used to identify the rows in a related table. The other choices are also important aspects of database design, but they do not directly relate to expressing relationships between tables. Minimum cardinalities refer to the minimum number of instances of an entity that must be involved in a relationship, identifiers are used to uniquely identify entities within a table, and attributes are the characteristics or properties of an entity.
