Andrew deals with several vendors and one of them is Navi Wholesale. Andrew often places orders for chocolate of different flavors at the same time. Each order is placed with one specific vendor. The vendors never consolidate multiple orders into one shipment, and always ship merchandise promptly. Usually, Andrew’s vendors can fill his entire order in one shipment. Occasionally, however, a vendor may be temporarily out of stock of a particular item. In such cases, the vendor waits until all the items become available and ship the entire order. The vendors do not allow Andrew to make partial payments of invoices or settle several invoices with one payment. Andrew has five bank accounts, and each payment can be made from only one of those accounts. Each transaction is processed by exactly one employee. 

1. Identify the resources, events, and agents for the accounting system of Jake’s chocolate store. Draw the REA diagram using Visio. Be sure to include all the cardinalities. 

2. Prepare a listing of the tables that you would need to create a working database. For each table, specify the primary key, the foreign key (if any), and at least 2 other attributes. 

3. Create the database in Microsoft Access. Link all the tables and enforce referential integrity. 

4. Create at least 5 records for each table. Assume that all purchases occurred in the months of January, February, and March in 2019, and each purchase order contains at least two different chocolate flavors. 

5. Create the following queries in Microsoft Access: 

a. Total dollar purchases in the first three months broken down by chocolate flavor. List item description and dollar purchase amount. 

b. All orders placed with Navi Wholesale that exceed $2500, sorted from the highest to the lowest. List order date, dollar purchase amount, and vendor name. 

c. All orders that have been paid for. List order#, order amount, and payment amount. 

d. All orders that were NOT received within 3 days of order. List order number, vendor name, date of order, and date of receipt. 

e. The average dollar amount of a purchase transaction.
