"powerful technique of entity relationship modelling from this definitive guide. In a lucid instructional style, Richard Barker shows how the data modelling technique can be applied to develop high–quality, integrated information systems."
Richard Barker (1990). CASE* Method: Entity Relationship Modelling, Addison–Wesley.
[Entity-Relationship Modelling is a method for designing a 'logical' database (as apposed to creating a 'physical' database). In the notation an 'entity' is a logical way of describing a database table. Each entity has properties, which are a logical way of describing database fields. Each entity will more than likely have a relationship with other entities, these are expressed in terms of either a 'many-to-one' or a 'one-to-many' or a 'one-to-one relationship. Note that it is not logically possible to have a 'many-to-many' relationship - in such cases an 'intersection table' is inserted.]
