Description

For Assignment #1 you will use MS Visio’s crow’s-foot notation template to produce an entity-relationship (ER) model based on the defined business rules listed below.

Business rules (entities are in bold)

  1. A cinema must contain at least one theater, and can contain many theaters. A theater can belong to one and only one cinema. (Note: this means that the crow’s-foot notation “1 or more” should abut the theater entity, while the notation “1 and only 1” should abut the cinema entity.)

    1. Cinema includes the following attributes: cinemaID (PK); cinemaName; cinemaAddress; cinemaCity; cinemaState; and cinemaZIP

    1. Theater includes the following attributes: theaterNum (PK); cinemaID (FK); theaterSeatCap; and theaterSound

  1. A theater must have at least one showing, and can have many showings. A showing appears in one and only one theater.

    1. Showing includes the following attributes: showingID (PK); movieID (FK); theaterNum (FK); showingDate; showingStartTime; showingPriceChild; showingPriceAdult

  1. A movie must have at least one showing, and can have many showings. A showing includes one and only one movie. (No double features!)

    1. Movie includes the following attributes: movieID (PK); movieTitle; movieRunningTime
