Assignment 3 Chapter 5 - UML Sequence Diagram Draw a Sequence diagram for Scheduler system for the scenario of adding new appointment The scenario begins when the user chooses to add a new appointment in the UI. The Ul notices which part of the calendar is active and pops up an Add Appointment window for that date and time. The user enters information about the appointment's name, location, start and end times. The UI will prevent the user from entering an appointment that has invalid information, such as an empty name or negative duration. Then all this info will be validated on appointments record. The appointments record the new appointment in the user's list of appointments records. Any reminder selected by the user is added to the list of reminders. After saving, if the user enters an appointment that clashes with an existing meeting, the calendar asks the user whether he/she intended to join that meeting instead. Hint: the underlined are class names (lifelines)

Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.
