Draw a UML use case diagram for the following scenario: The following describes an online service for providing 'meals-on-wheels'. Meals on wheels are provided to people who are unable to either cook a daily nutritional hot meal for themselves or obtain this in any other way. The service is provided by the local government, or council, and is only provided to those who have a need for it that has been assessed by social services. The meals-on-wheels service provides customers the possibility to order cooked or frozen meals for delivery on a daily basis. The customer should be able to select a type of meal (cooked, frozen), a desired quantity (i.e. number of people), dietary requirements (e.g. vegetarian) and a meal type (e.g. breakfast, lunch, dinner). Additionally, the customer can choose between daily or weekly delivers, for frozen meals. In order for the customer to be able to place an order, he or she must have an account. The customer can create an account by choosing a username/password combination. Furthermore, his or her address and service entitlement (SE) number (provided by the local government organisation) can be linked to the account, which is required information when placing an order. Once a customer has provided the information for an order, the system checks if all required information is there, either given in the order or in the account details. If any information is missing, the system will inform the customer that it needs to be added before the order can be placed. Once all information is in place, the order is placed, and the SE number is sent to the local government for validation. If the local government validates the SE number, the order is finalised. An administrator monitors whether sufficient food supplies/ingredients are available to prepare and cook the meals ordered. Whenever the food supplies are running low, order must be placed at appropriate supplier.
