You have been requested to design a software application for a large toy company that provides an online product catalog for ordering all types of toys and games. There are four types of users:

• Guests
• Members (credentials and history saved)
• Titanium Members (achieved after spending $10,000 in one calendar year)
• Administrators

Products will have typical information stored on them to include name, category, description, age group, price, weight, and much more. There will also be a rating system for products that members and titanium members can contribute to. Guests can review the rating information, but not contribute to it.

The software application should have a reporting function, so sales information needs to be retained.

Review the requirements above and, using Visio or any other diagramming software, create Class diagrams for User, Product, Rating System, and Sales. Explain each diagram and how the classes interrelate.

Note: Templates can be found in Visio by accessing the UML System template.

Once you have completed your diagrams, copy them into a Word document.
