Sue's Flowers Expenditure Cycle (ERD Project to be completed and submitted by students)

• Now that you have helped Sue develop the ERD for the Revenue Cycle, Sue has decided to develop a database system to track her purchases, floral inventory, accounts payable and cash payments. 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 expenditure system as follows:
• Whenever flowers are needed, a purchasing agent enters a purchase order for the items directly into the computer system. To accommodate all of her floral needs, the purchasing agent may need to prepare several orders, as Sue orders flowers from many different vendors. Vendors are selected based on information maintained about their delivery performance and prices for floral items they are approved to sell. This information is maintained by a special purchasing clerk who gets catalogs and other materials from vendors and enters the data into the system using a special screen. The purchasing agent views this information using a special inquiry screen within the computer system. The purchasing agent may order several types of flowers from a single vendor on one order. Sue approves and prints these purchase orders and sends them to the vendors.
• A floral designer records the receipt of flowers from a vendor on a special screen in this accounting system. At the end of each month, an accounts payable clerk creates checks to pay for all amounts charged through the end of the month. Once the checks are created, Sue authorizes the checks, prints them and mails them to vendors. Sue also uses special screens in the computer system to perform maintenance for inventory items (add, modify and delete items from the file), and to record disposal of old or damaged flowers.

Problem 1: Prepare an ER diagram describing Sue's database.
