Question description

Kim Burke is the owner and operator of a small flower shop, Kim'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 system 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 Kim. When Kim completes delivery of the sales order, an accounts receivable clerk records the delivery on a special screen. When delivery entry is completed, Kim 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. Kim takes the all of the cash receipts for a day and prepares a single deposit slip form and makes the deposit. Kim later enters the deposit information from the paper form into the computer. 

 Prepare an REA diagram describing Kim's database. You may repeat a box for an individual entity if necessary to make your drawing neat. Kim 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. (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. 

 Prepare the context diagram and the level 0 DFD.
