Post Entities List - First Pass

Go through each requirement and determine the entities it's describing. There are no marketing department, manager, sales team, nor sales person entities. They indicate other more general entities. Reduce the number of your entities using recursion and types.

For example: WEB_CUSTOMER, IN_STORE_CUSTOMER would be modeled as CUSTOMER with an attribute named CustomerType. CustomerType would have the values 'web' and 'in store'.

Post you entities in UPPER_CASE as a vertical list below. Write one entity per line.
