The following problem is based on the previous assignments (Assignment-1 and Assignment-2). For your convenience, the same problem description is given below: Members join the system by registering online (username (email), password, address, phone no) and including a credit card to pay the membership fees. Most memberships are for one year, but member- ships as short as two months are available. Throughout the year, the streaming service offers various discounts on its regular membership prices (e.g., two memberships for the price of one for Christmas). It is common for members to pay different amounts for the same length of membership. The service sends out reminder emails to members asking them to renew their memberships one month before their memberships expire. Some members have become angry when asked to renew at a much higher rate than their original membership contract. That is why the organization wants to track the price paid so that the manager can override the regular prices with special prices when members are asked to renew. The system must track these new prices so that renewals can be processed accurately. The manager wants the system to track each time a member visits the site. The system will then identify the heavy users and generate a report so that the manager can ask them to renew their memberships early, per- haps offering them a reduced rate for early renewal. Likewise, the system should identify members who have not visited the site in more than a month so that the manager can email them and attempt to re-interest them in the service. Draw a class diagram for the streaming system. Add attributes and methods when necessary. You do not have to include getters and setters for attributes. Visibility modifiers (public, private, etc.), multiplicities, attribute types, method return types are required.
