Question

Sue’s Flowers Revenue Business Process Project Sue Hernandez is the owner and operator of a small flower shop, Sue’s Flowers. She has decided to develop a database system to track her sales, inventory, accounts receivable and cash receipts. This system is used for large orders that are arranged in advance. However, she does not have time to do the development herself. Therefore, she has hired you to design and implement the system for her. She describes the requirements of her revenue system for processing wedding orders as follows: Whenever a customer comes in to place an order, a sales clerk enters a Sales Order directly into the computer system. The sales order lists all of the floral inventory items the customer wishes to purchase. The clerk then prints the sales order and gives a copy to the customer. If this is a new customer, before entering the sales document, the clerk must enter the customer's basic information such as name, address, etc. Additionally, credit for new customers must be approved by Sue.In addition to transaction information, Sue tracks history information for each customer, showing all of the flowers purchased by each customer, and quantities of each type. This allows her to target market specials to each customer, and more quickly assess each customer’s needs when they come into the shop.This information is updated automatically by the computer system when the goods are delivered to the customer.When Sue completes delivery of the sales order, an accounts receivable clerk records the delivery on a special screen. When delivery entry is completed, Sue prints the invoices and sends them to customers. When customers send in their payments, a sales clerk records the cash receipts on a special input screen. Sue takes the all of the cash receipts for a day and prepares a single deposit slip form and makes the deposit. Sue later enters the deposit information from the paper form into the computer.

Prepare an ER diagram describing Sue's database. (State any assumptions you believe you have to make in order to develop a complete diagram). Sue would like for you to consider that, eventually, as new stores are opened, she will have store managers in each store that will perform the tasks she now performs. As a result, the system should be planned to always store information about the employee associated with transactions, whether that employee enters information, performs a task (such as delivery) or formally authorizes the transaction.

Hints:

1. A particular sales order is always delivered and invoiced all at the same time. Deliveries include information for only one Sales Order.

2. A single cash receipt may pay for several deliveries. A single delivery may be paid for with several different cash receipts. List and describe all of the recording, maintenance and reporting information processes that are described in the narrative.
