1. Anentity type is a representation of a person, place, thing, event or concept of interest to a retailer. Examples of entities include Customer, Item, Retail Store, Web Site, Purchase Order, Retail Transaction - and the list can go on to hundreds of nouns. Within the ARTS data model each entity type is defined in business terms. In an entity diagram, entity types are represented as rectangles. Each entity type has a unique, singular noun phrase assigned as its name. In a relational data model, each entity type instance is uniquely identified by a primary key. A primary key is one or more attributes that have values used to uniquely identify and distinguish each entity type instance from each other.
