Here is listing of the tables for the database for this assignment.

SELLERS(SellerNum, SellerLastName, SellerFirstName, SellerStreet, SellerCity, SellerState, SellerZip, CRate)

BUYERS(BuyerNum, BuyerLastName, BuyerFirstName, BuyerStreet, BuyerCity, BuyerState, BuyerZip, BonusLevel, SellerNum)

PRODUCTS(ProductNum, Description, NumberInStock)

STATEMENT(StatementNum, StatementDate, BuyerNum)

STATEMENTLINE(StatementNum, ProductNum, Quantity, ItemPrice)

Note: Please recall that the id numbers for each table are numeric (integer) value, the commission rate (Crate) and the ItemPer (individual quoted price per item) are numeric with 2 decimal places, and the quantity (quantity of the products ordered) and NumberInStock (number of items in stock) are numeric (integer) values. Additionally, the states use the common 2 character state abbreviation and the statement date is a date value. All other values are character values.

1) Using the above database schema, draw an entity relationship diagram using the Crows Feet notation. Justify, in writing, the decisions you make regarding minimum and maximum cardinalities.

Regarding the ERD, you can do it anyway that you want to but you need to put the diagram into a Word document. You can:

a) Draw it on paper, scan it, and insert it in your document, or

b) Use Word to create the diagram using shapes from the Insert menu.

c) Use Visio (download for free from the Azure site where you got Access) and insert the diagram into your document, or

d) Use MySQL and insert the diagram into your document (Download and install MySQL Workbench).

Additionally, respond to the following questions:

2) Write a SQL statement to list all of the buyers’ first and last names that live in Alaska, Delaware, Florida, Michigan, or Wyoming.

3) Write a SQL statement to display the different cities that sellers live in — only one of each city.

4) Write an SQL statement to display the seller’s first and last names that is assigned to each buyer (you should list the buyer’s name and their assigned seller’s name).
