Consider the following description for a simple online bookstore. Which relationships are identifiable in the online bookstore description? Please specify the source and destination classes for each relationship along with its type (i.e., Generalization, Association, and Aggregation). Customers search for and select books, order them, provide credit card information to pay for them, and provide delivery information. Information on valid sales (sales for which the credit card is approved) is forwarded to a warehouse where ordered books are collected and shipped. Invalid sales are declined
