entity-relationship model

database, specification An approach to data modelling

proposed by P. Chen in 1976. The model says that you divide

your database in two logical parts, entities (e.g. "customer",

"product") and relations ("buys", "pays for").

Entity-relationship diagrams can be used to represent a model.
