Create a use case model with:

A museum has asked you to develop a system to manage data on their visitors.

The proposed system will be web based and operated by an museum employee as visitors enter the museum. Each visitors information should be captured. These details include name, address, email, and phone number.

Some visitors may also be members of the museum. Details about their membership should be captured as well. These include membership ID, membership start date, membership expiration date, and member type. Each member can bring a guest for each of their visits. The museum wants to keep track of details about the guests that members bring as well. Details include guest name, guest address, guest email, and guest phone number.

Visitors who are not members may want to become members. Employees at the museum should be able to create new memberships for such visitors.

In addition, the system should allow employees to cancel memberships or to change a membership to a different type of membership. They have different levels/types of memberships gold, silver, and bronze. Bronze members can bring one guest each for each of their visits. Silver members can do that and also receive free tickets to special events. Gold members receive all of that and also receive two free parking passes.

Employees, along with another guest of their choice, can attend all events at the museum free of charge.
