---++ER Homework 1 This homework is designed to get you familiar with Oracle's Data Modeler software so that you can design database systems. ---+++Assignment Create an ER diagram to model the relationship between food items, a menu, and a bill for a restaurant. You may create unique ids if you wish but you should also indicate if there is a combination of attributes that could also be a key. Use common sense to decide about optional conditions * An item has: * a description * a short name * a size * a price * a set number of calories * A menu * There are two menus: An adult and a child * Menus have many items on them * A bill * A bill has a date and time * Has a number that is unique only for a given date and time * Has a bunch of items on it (some of which can be duplicated) ---+++Submission requirements * Your diagram must be done using the class standard format * Your diagram must contain your name * Your diagram should fit nicely on one page (all I should have to do is print it) * You need to combine the file and the folder together into a zip file and submit that zip file.
