Make a database for a gourmet burger restaurant called Burgers by Design. The restaurant owner, Bob, has been running his business with pen-and-paper, but has decided to switch to an IPoS (Internet Point of Sales) System. This system will allow users to make an account and order their burgers either online (for pick up) or in store using a tablet. Burgers by Design allows users to build their burgers by paying for each part of the burger separately. Bob wants all of his menu information to be included in the database: items, descriptions (not shown on the menu), prices, and allergen information. He also wants full user information for advertising: name, phone, email, address, etc. He also wants to keep track of what each user has ordered in the past, so that they can easily order it again.

For this assignment, create an ERD with entities, relationships, attributes, keys, and constraints (80 pts) and identify the participation constraints. Also, determine a weak entity that can be added to the ERD and add it.
