Ask a database or systems analyst in a local company to show you an E-R diagram for one of the organization’s primary databases. Ask questions to be sure you understand what each entity, attribute, and relationship means. Does this organization use the same E-R notation used in this text? If not, what other or alternative symbols are used and what do these symbols mean? Does this organization model associative entities on the E-R diagram? If not, how are associative entities modeled? What metadata are kept about the objects on the E-R diagram?
