UNIT 4 RESEARCH PROJECT 2
Unit 4 Research Project
Part 1. Your database. (90 points)
a. Pick two tables that have a 1:M relationship from the database you designed in your
IT520 or IT525 course. If you have not taken IT520 or IT525, use the sample project in
the Unit4.DatabaseDesign document in Doc Sharing. Show the data dictionary and
sample data for those two tables. Using your data dictionary as a template, give the
CREATE TABLE statements for those two tables, including Primary Key and Foreign
Key constraints. (30)
The two tables I have selected are CUSTOMER and INVOICE, a one to many
relationship.
UNIT 4 RESEARCH PROJECT 3

I create a database
CREATE DATABASE robot;
I select the database
USE robot;
The CREATE TABLE statements are
(Ben-Gan, Sarka, & Talmage, 2013).
UNIT 4 RESEARCH PROJECT 6
b. Give INSERT statements that would insert at least five rows of data into each table. (10)
The INSERT for the Customer table
The INSERT for the Invoice table
(W3Schools, n.d.).
UNIT 4 RESEARCH PROJECT 7
c. Show the results of SELECT * FROM <tablename> for each of your tables. Paste each result
set into your Assignment Word document. Then paste into Word a screen image of the two result
sets. The Object Explorer pane should show the Databases folder expanded to show your
database, and its Tables folder expanded to show your two tables. [Eliminate white space in
SSMS so the characters in the screen image are readable without magnification. Use
ALT+PrintScreen to get an image of only SSMS and not the entire desktop.] (10)
The Customer table
The Invoice Table
d. Create a view for your database. Explain the purpose of the view, i.e., state why you feel the
view is necessary. Give the CREATE VIEW code for your view. (15)
This view created to reduce the complexity of the frequently used invoice table. Normally, the
invoice table has possible values for Invoice_ID, Date, Subtotal, Tax, Total, and Customer_ID.
For the use of the invoice itself, all that is really needed is the Invoice_ID, Date, and Total, thus
the below has been created.
UNIT 4 RESEARCH PROJECT 8
e. Update data in your database. Explain the purpose of the update. (10)
An update was required to the robot database due to Florida increasing its sales tax from 6
percent to seven percent. To make this change, the following UPDATE was created:
f. Show the results of SELECT * FROM <tablename> for the table(s) that have updated data.
(2.5)
These are the results from the above update (the updated tax rows are outlined):
UNIT 4 RESEARCH PROJECT 9
g. Delete one or more rows of data from a table in your database. Explain the purpose of the
delete. (10)
Due to a recent complaint from customer Lee Moss, the Robot Emporium is refunding the
customer’s purchases, and deleting the records from the database. The following shows the
delete. The invoice ID’s that must be deleted are invoice numbers 1 and 2.
h. Show the results of SELECT * FROM <tablename> for the table that had a row deleted. (2.5)
UNIT 4 RESEARCH PROJECT 10
Part 2. Inline Table-Valued Function (10 points)
The following view returns the total number of orders for each customer:
Create an inline table-valued function named Sales.fn_NumOrdersByCustomer that returns the
custid and the total number of orders for a specified custid.The Function
(Microsoft, 2014).
UNIT 4 RESEARCH PROJECT 11
The returned output for the specific CustID 2 is
