a. Read out the following scenario and i. identify classes, attributes and operations. ii. After identifying classes find out their relationships and iii. draw a complete class diagram of the application. The system to be designed is an android application. The application to be designed is an online table reservation app. The app should graphically represent the restaurant in order to overcome the problem of table reservation. Sometimes user needs to reserve a specific table at a specific location but it is difficult to get the desired table for what he is planning.

He can also choose the menu of the reservation and there should be an option to calculate the real time bill of the order, so that user can manage his budget as well. There should be a feature for online payment for users to confirm his reservation. The user should also be allowed to add a reminder to get notification for reservation. The app should provide the restaurant layout with table capacity and location at real time to the users as well. b. Draw a UML sequence diagram fo the following scenario The application to be designed is a hardware based application. The Hardware Unit will be attached to the fridge that senses the food items in the pantry. The hardware should send the data to the attached user application specifying the food items present in the fridge. Based on the available items, the AI algorithm implemented in the application will suggest different recipes and menus to the users. The suggestions should consider the health status of the user before suggesting any recipe. It can also give instructions through personal assistant on how to cook the food. The application should also keep a check on the expiry date of the food items. In addition to this, the app should alert the user about the exhausted food items and allow the user to place an online order for exhausted items.
