Exercise: Employee Timecards

You work for a startup IT company that performs web development for outside companies. In any given day, you may be working on more than one project. Projects are typically group projects so others may be working on the same project on the same day that you are.

To keep track of what projects you and your co-workers are working on every day, each employee must create entries into the time system every night before they leave for that day. That time entry will list one project and the number of hours the employee worked on that project that day. There will be entry every day for each project that each person worked on that day.

Describe each class in English.

Draw the class diagram, including association classes if required.

Describe each association in English (both directions).

Draw the relation scheme.
