Also, remember to show cardinality (1:1, 1:M, M:N); you can use the cardinality notation or the crow’s foot notation. Remember that this is a graphical language, and you must follow the shapes of the elements in the diagram.

Database Management Jill Bill Marketplace is a business located in Florida. Within the JBM compound, you can purchase many types of products that are related to a specific category, for example, books or antiques. JBN does not own any of the stalls that sell products, rather they rent them out to small vendors. Each vendor has to pay a monthly fee to use the Marketplace.

The small vendors will report to the category managers on the nature of their stock and if and when restocking is required. All category managers report to the third…
