Attributes

19 January, 2016 - 14:28

Each entity is described by a set of attributes. E.g. Employee = (Name, Address, Age, Salary).

Each attribute has a name, associated with an entity and is associated with a domain of legal values. However the information about attribute domain is not presented on the ER diagram.

In the diagram, each attribute is represented by an oval with a name inside.
