In the outbreak of Covid19 the demand for healthcare application has enormously gone up. XYZ Pharmaceutical Company intends to develop a healthcare application. The company stakeholders are in a rush to develop the application and market it quickly. The application has Treatment, Team, Progress and Today modules. The treatment module has further Medication, Measurement, Activity and symptom check sub modules. The user can add up to 6 medications and can set reminders for them. In the team module the user can add Appointments, add healthcare professions and invite friends. A user can add maximum of 3 appointments in a day, however there is no restriction on adding any number of healthcare professionals. The Progress module displays information in charts format once the reminder time is confirmed. The Treatment module displays the added Medication, Measurement, Activity and Symptom Checks. A user can add as many Measurements, Activities and Symptom Checks and the results will be displayed on the Treatment view, however, the Medication results for the Treatment view is restricted to 6 only. Whenever, a user enters a medication the medication will have Name, type, quantity, and time for alarm. A) Draw a Class Diagram for the proposed application. Also label the diagram with appropriate associations and multiplicities. B) There is a drawback in UML Models: of being STATIC in nature i.e. the constraints on the objects has limitations. Argue with reasons that where in your solution the class diagram will fail to specify the constraints.
