Use the following additional information to add new elements to your diagram in question 2. You should have two distinct ERD for each of question 2 and 3. We were able to obtain the following information about BurgerBay: BurgerBay CEO realized that more information about the company should be shared with you in order to have a complete database: Through the brand expansion, it was decided to have two different types of restaurants. Some will offer a complete dine-in experience and will have a maximum customer capacity which should be kept in record. The second type of restaurants is considered an "Express" type as it only allows for take-out and drive-thru. For this second type, it is important to record the open and closing hours of the drive-thru. Note that some of the restaurant offering a dine-in experience can also only offer take-out and drive-thru. Such restaurants are therefore considered both "Dine-in" and "Express". About 20 different and non-interchangeable types of employees works at BurgerBay restaurants. Among them two types require special attention: Managers are in charge of restaurant and should be reachable through their office phone number, which is kept in the database. Cooks are the second type of employee with extra information. Cooks are assigned to cooking stations and it is important to save the name of each station. To avoid confusion cooking stations can be identified using a unique ID number. Note that while a cook must be assigned to a cooking station, it is not unusual for a cook to rotate across multiple stations. A cooking station has room for only one cook at a time and it is possible for some stations to have no cook assigned to it
