Question

Please use Umlet. Draw a UML domain model class diagram using the following notes on the classes, attributes and relationships discovered by the analyst so far: Your head analyst has been interviewing the department faculty about the course scheduler they would like to have developed. So far she has found a few classes. Your job is to create the UML Class diagram. Here is the information we have so far: Classes: • The Room class. All rooms have a building letter (char) and a room number (4 digits) that identify them. Rooms have number of seats (number), they may or may not have student computers in them (boolean). A room may or may not have A/V equipment in it (boolean). • The Course class. Courses have a course code (String), a course description (String) and number of credit hours (number). A course may have a prerequisite course(String). • The Section class. Section class is an abstract class. It represent an instance of a scheduled course. A Section has a section ID (number), a year (String) and a semester (String). • The LectureSection class. A LectureSection class is a subclass of the Section class. It has day(s) of the week scheduled (String) a start time (String) and end time (String). • The HybridSection class. A HybridSection class is a subclass of the Section class. It has the day of the week scheduled (String) a start time (String) and end time (String), and a Learning Management electronic course number (number). • The Online class. A OnlineSection class is a subclass of the Section class. It has a Learning Management electronic course number (number) and a proctored event flag (boolean) that indicates if there is a proctored event. • The Faculty class. Faculty have an employee ID (number), first name, last name, and department (Strings) Relationships. • LectureSection, HybridSection and OnlineSection are all subclasses of the Section class. • The Section class has a Course and a Course can have zero or more Sections • The Section class has a Room class and a Room class can have zero or more Sections • The Section class has zero or one Faculty classes and the Faculty class has zero or more Sections.

Answer 1

Done. The following realtionships are depicted in the UML. No methods are added as nothing is mentioned in the problem description: Please leave a comment if you have any doubt.

Section class has following subclasses:

LectureSection, HybridSection and OnlineSection

The Section class has following relationships:

• has a Room class
• has a course
• has zero or one Faculty

Course class:  can have zero or more Sections

Room Class: can have zero or more Sections

Faculty class:  has zero or more Sections.
