CIS 336 Final Exam 4 Sets of Answers
==============================================
CIS 336 Group Project
www.cis336study.com
This project is designed to touch all aspects of the fundamental concepts
of database design and logical data modeling covered during the class.
Each student will be responsible for designing, developing, and
demonstrating the functionality of a database created based on a set of
business specifications that you create. At the end of the session, each
student will submit a report that includes the logical and physical design
of the database and demonstrates the database's ability to deliver
meaningful reports. All aspects of the project will be covered during the
week or weeks prior to a deliverable, and each task deliverable in the
project will be supported through the exercises and labs done in the
course.

Guidelines
You will create a proposal for a commerce business of your choosing.
This can be an actual or fictional business that sells products and/or
services. You will determine the business rules and report requirements.
Entities that must be included in your model are the following.
Customer
Product (or Service)
Order
Project Deliverables
This task is broken down into four deliverables.
· Task 0
· Task 1
· Task 2
· Task 3
Remember that this is a work in progress and in all likelihood, you will
have to make numerous changes to your tables and schema as you go
along. These changes are to be expected and are a normal part of the
database design and implementation process.
Please refer to the sections below for details regarding deliverables for
each task.

Task 0
The first task is to create your business narrative. Some of the questions
that you should address include (but are not limited to) the following.
· What is the name of your business?
· Who will be the users of the system (managers, employees,
customers)?
· What product(s) and or service(s) does it sell? Be specific.
· Who are the customers? What is the customer base?
· What sales and distribution channels are used?
· How are payments made?
· Are products delivered or shipped to customers in some way?
· Are sales reps involved? Are they paid on commission?
· What type of reports are needed by the business?
Please include as much detail as possible in order to provide a
foundation for Task 1. Submit your proposal as a Word document. Note
that this proposal may be revised in the coming weeks as your
understanding of the database modeling process grows.
Task 1

Develop a detailed logical model of your database based on your
business scenario submitted for Task 0. Your data model will include an
entity-relationship diagram (ERD) developed with Microsoft Visio or
MySQL and a data dictionary (DD) developed with Microsoft Excel.
Note that your deliverables each week include any revisions to the
previous task.
Submit your Task 1 deliverable as a zip file including the following.
· Task 0 proposal (with any revisions or updates)
· Your ERD copied to a Word document that fits on a single 8 x 10
page
· Your DD (Excel file)
Task 2
First, make sure to make any necessary revisions to your logical model
based on Task 1 feedback. Using MySQL, write the statements to
develop a physical model of your database by creating the tables and
constraints based on your Task 1 logical model. Be sure to use your
ERD and data dictionary and create all constraints appropriately.
Once your tables are created, you will populate them with data using
MySQL statements to insert records into the database. You should insert
a minimum of five records into each table and more where necessary to
ensure that the data in the database is sufficient to allow for each of your
reports to be tested.
The result will be a script file that includes statements to

· DROP all tables;
· CREATE all tables with constraints;
· INSERT data into all tables; and
· SELECT data from all tables to show the data in each table.
Name this file yourname_task2.txt.
Also create a Word document that shows the structure of each table and
the data in each of your tables (copy and paste from MySQL). Name this
file yourname_tables.docx.
Note that your deliverables each week include any revisions to a
previous task.
Submit your Task 2 deliverable as a zip file including the following.
· Task 0 proposal (with any revisions)
· Your Task 1 ERD (with any revisions)
· Your Task 1 DD (with any revisions)
· Your Task 2 script file to create and populate tables
(yourname_task2.txt)
· A Word document showing all tables and data
(yourname_tables.docx)
Task 3
Your final task is to use your tables for an update and for reports. There
are two requirements.

1. You will demonstrate an update that includes two tables and uses a
subquery. Make sure to prove that your update executed correctly by
showing data in the tables before and after the update.
2. You will also develop at least four meaningful reports. One must
include a join, one must use a subquery, and one must use an aggregate
function. You need to describe the business requirement of the update
and each report. Note that numeric PK values are not often meaningful
to a person looking at the report. You will create a script file that has
each of the queries called yourname_task3.txt. You will also document
the results of this task in a Word document called

CIS336 Lab 1: Normal Forms and Entity Relationship Diagrams
Introduction
In this exercise, you will analyze a de-normalized data set presented in
the form of a spreadsheet. You will next construct a series of
dependency diagrams, transforming the evolving data model from
First Normal Form (1NF), to Second Normal Form (2NF), and finally
to Third Normal Form (3NF). When the model has reached 3NF, you
will construct the Entity Relationship Diagram (ERD) depicting the

logical design of the database. Your ERD will use Crow’s Foot
notation to denote the relationships between tables.
Sample Exercise, With Solution
Before completing your lab, please review this example problem. The
diagram below is a partial depiction of a business spreadsheet for a
retail store operation. The store sells books. Books have a 13-digit
International Standard Book Number (ISBN), a title, a publisher, and
a unit price. Invoices track sales of books. An Invoice contains one or
many line items, with each line item reflecting the sale of one or more
copies of a specific book. Every publisher has a company name, and a
publisher code.

BookSales

1. Using the BookSales table structure shown above, draw the
dependency diagram, and show all dependencies, full, partial, and
transitive.
Figure 1 -solution 1
Discussion: A composite primary key consisting of InvNum + ISBN13
can be constructed, ensuring that all rows are unique. All remaining
attributes are shown to be dependent (at least partially) on this
composite key, so the table is 1NF. Further analysis shows that
InvDate is dependent on only part of the key (InvNum), and that
unitPrice, PubCode, and BookTitle also depend on part of the key
(ISBN13). A transitive relationship is also revealed: PubName truly
depends on PubCode, which in turn depends on ISBN13.
2. Using the answer to exercise 1, remove all partial dependencies and
draw the new dependency diagrams. For each new table created,
specify its normal form (1NF, 2NF, 3NF).
Figure 2- solution 2
Discussion: To achieve 2NF, we must remove partial dependencies.
This is done by decomposing into three tables, and three dependency
diagrams at this stage. Notice that the Transitive relationship has not
yet been addressed.
3. Using the answer to exercise 3, remove all transitive dependencies,
and draw the new dependency diagrams. For each new or revised
table, specify its normal form.
Figure 3 – Solution 3

Discussion: The transitive relationship has been removed by creating
the Publishers table, in which PubName is fully dependent upon
PubCode. Pubcode also persists as a dependent attribute and Foreign
Key in Books. All tables are now in 3NF, and have been given
meaningful names reflecting the entities they represent. LINEITEMS
represents the collection of line items for all invoices. Invoices
represents the collection of Invoices for all customer orders. Books
makes up the list of all books available for sale (whether they have
ever been ordered or not). Each book has a publisher, and the
publisher code and Name reside in the Publishers table.
4. Draw the ERD for exercise 3, using Crow’s Foot notation.
End of Sample Exercise.
Student Exercise
The student exercise for this lab is similar to the sample exercise
presented above.
Consider the following spreadsheet containing information about
customers, their shipping and billing addresses, and the countries
corresponding to each of those addresses. A customer may be
associated with zero to many addresses. A customer may have 0 or 1
default billing address. A customer may have 0 or 1 default shipping
address. Each address may be associated with 0 or 1 countries, while
each country may be associated with 0 to many addresses.

CIS 336 iLab 2 The Expanded Entity Relationship Diagram
www.cis336study.com
CIS336 Lab 2: The Expanded Entity Relationship Diagram
LAB OVERVIEW
Scenario and Summary
This lab introduces the next step in creating a data model, the Entity
Relationship Diagram (ERD). You will be given a business scenario
for a University Medical Center, which is a small community hospital.
The business specifications will outline a number of things about the
business, some of which will apply directly to the database you are
being asked to model. There is a table that lists the entities (tables) that
will be needed for the database and related attributes (columns) for
each entity. There is also a column that lists specific information about
the entity that will be helpful in determining its relationship to other
entities within the model.

Be sure to include the minimum and maximum occurrences of each
relationship (cardinality) and to supply a name to the relationship that
will work in both directions. Make sure to use Crow’s Feet notation in
your ERD.
Narrative/Case Study
The University Medical Center is a small, community hospital. A new
hospital administrator has recently been hired by the Board of
Directors, and directed to right-size patient care and pharmacy
services and improve profitability. The hospital operates three clinical
facilities: the main hospital, a mid-town clinic, and an Urgent Care
location. The hospital also offers selected in-home care services. Many
of the patients are repeat or regular patients who receive regular
treatment for various conditions, and many utilize the hospital’s
pharmacy services for prescription medications.
The pharmacy dispenses about 3,000 different prescription
medications of various kinds. Every prescription is associated with one
patient, and is logged by the dispensing clinic. The new administrator
wants to know which drugs are most prescribed, and also which are
the most profitable.
The following is some general information about the organization and
its current processes.
• The hospital operates three clinical facilities.
• A healthcare worker logs in at a facility at the start of a shift and logs
out at the end.
• The name, address, Social Security number and other information is
recorded for every healthcare worker.

• All healthcare workers have one billing rate, which is determined by
their job description.
• Each medication dispensed by prescription is linked to both the
prescription number and the medication ID number, recording the
item price and the quantity dispensed.
As a convenient and affordable means of providing hospice care,
palliative care, and convalescent care to patients that need
occasional/intermittent skilled nursing, but do not require
hospitalization, the hospital offers limited in-home care. Recording of
in-home care includes the healthcare worker ID, their departure time
and return time, and also the prescription ID for any prescriptions
administered by the healthcare worker in the home setting.
The hospital administrator would like to know what home-care visits
have been made to whom, by whom, when, and how long they took.
There is concern at this point that the cost of providing limited home
healthcare is not providing adequate return on investment, and the
program should be revised or discontinued.
Requirements
You have been asked to develop a logical data model for University
Medical Center based on the information given to you by the new
hospital administrator and their staff. Through analysis of the nouns
and verbs in the case study above, you have accumulated the following
entity, attribute, and relationship information shown in the table
below. The attribute list may not be complete. If you determine that
additional attributes are needed to better define an entity, then you
should add them.

Entities Attributes and Relationships for University Medical Center
(Parallel Lab Exercise):
Entity Attributes Relationships
HealthcareWorkerHealthcareWorkerID, LastName, FirstName, SSN,
Address, City, State, Zip, Phone Number, HealthcareWorkerTypeID A
healthcare worker can belong to any one of the three job categories,
but can belong to one and only one of the three. healthcare worker has
names and other contact information.
HealthcareWorkerTypeHealthcareWorkerTypeID,
HealthcareWorkerTypeDesc, HourlyBillingRate A healthcare worker
can be either a physician (diagnoses, prescribes medication), nurse
(provides physician-ordered treatments, administers medications), or a
pharmacist (dispenses, delivers medication).
ClinicLogClinicLogID, ClinicID, Login, Logout, HealthcareWorkerID
Patients may be treated by a healthcare worker at a clinic and can be
tracked by the clinic log number. A healthcare worker must sign into
the clinic before he or she can serve patients, and must sign out when
finished treating patients at that clinic. A healthcare worker may serve
portions of a shift at more than one clinic.
Clinic ClinicID, ClinicLocationDesc, AMAAccredNum The hospital
operates three clinical facilities: General Hospital, Midtown Clinic,
and Urgent Care.
InHomeCareInHomeCareID, HealthcareWorkerID, PrescriptionID,
DepartTime, ReturnTime. Relates to both the healthcare worker and
the prescription entities. This entity will help track provision of home
healthcare. A healthcare worker can provide many home visits but a

prescription is administered on a home visit by one and only one
healthcare worker.
Method MethodID, Method Description Relates to medication and
identifies the method of administration, for example, oral, injection,
and so on.
Medication MedicationID, MedicationName, Dosage, Cost,
QuantityOnHand, LastPurchasedDate, ReorderMinimum Identifies
the medication the hospital pharmacy dispenses. One or more
medications can be dispensed per prescription. The quantity on hand
allows Pharmacists to determine the inventory levels. The reorder
minimum can be used to determine when the inventory level has
reached a reorder point.
Prescription PrescriptionID, MedicationID, BillingAmount,
TransactionDateTime, ClinicLogID, PatientID A prescription is
identified by a single prescription order. Prescriptions are
• made to one or more patients but only one patient at a time;
• made by one or more pharmacists but only one pharmacist per
prescription;
• recorded on one or more clinics but only one clinic per prescription;
and
• administered by one or more nurses but no one prescription can be
administered by more than one nurse.
PrescribedMedicationPrescriptionID, MedicationID, ItemPrice,
QuantityDispensed Prescribed medication is part of a prescription and
records medication dispensed per prescription. Prescribed medication

must be able to associate multiple medications sold on a single
prescription number.
Patient Patient Number, First Name, Last Name, Address, City, State,
Zip, Phone Number A patient can be associated with multiple
prescriptions, but any one prescription is to one and only one patient.
A prescription can occur without a patient registering in the system
(e.g., an unconscious patent arrives by ambulance in the emergency
room and receives life-saving emergency treatment).
Using an appropriate drawing/data modelling tool, develop an ERD
that meets the following guidelines.
• Draw the entities with their attributes.
• Indicate the relationships between the entities using Crow’s Foot
notation. You will need to determine the cardinality and optionality for
each direction of the relationships. Some of the Foreign Key
relationships are identified in the graph above but not all. Be sure you
identify and account for all Foreign Key relationships.
• Add a name (in both directions) to the relationships. Remember, if
you can verbalize the relationship in both directions, then you
probably have a valid relationship.
Deliverables
The deliverable for this lab will be your completed ERD as a single MS
Word document using copy/paste or imported as an image from your
drawing/modelling application, cropped and sized appropriately (it
should fit on a single page), and named lab2_solutions_yourname.
LAB STEPS
STEP 1: Drawing Entities and Attributes

Back to Top
Be sure to include all of the entities that have been defined. You need
to include at least the primary and foreign key attributes where
applicable in your diagram.
STEP 2: Add Relationships
Back to Top
Be sure that you link all entities based on PK to FK relationships.
There may be a case where you need to identify a combination PK and
if so make sure that all of the relationships involved are defined. Be
sure that you have set your drawing/modelling tool set to show Crow’s
Foot notation. Also, be sure that you are defining the correct
cardinality for the relationships.
STEP 3: Naming of relationships
Back to Top
If your drawing/modelling tool creates a default name for
relationships, do not simply accept this default without due
consideration. There may be some relationships where the default is
applicable, but in most cases you will want to explicitly name the
relationship. Be sure that you have provided a verb phrase for both
directions in the relationship.
This is the end of lab #2#4.

CIS 336 iLab 3 Building the Physical

www.cis336study.com
CIS-336: Lab 3: Building the Physical
LAB OVERVIEW
The lab for this week addresses taking a logical database design (data
model) and transforming it into a
physical model (tables, constraints, and relationships). As part of the
lab, you will need to download the
zip file titled CIS336Lab3Files from Doc Sharing. This zip file
contains the ERD, Data Dictionary, and test
data for the tables you create as you complete this exercise.
Your job will be to use the ERD Diagram found below as a guide to
define the table structures and
constraints using both CREATE TABLE and ALTER TABLE
statements. Once this has been done, you will
need to write the INSERT INTO TABLE statements to insert the data
provided into the table. The data
should verify that the constraints you have created are valid and define
the correct referential and data

integrity constraints asked for. Lastly, you will write SELECT
statements to query the tables and verify
the data was populated. Please use exactly the data provided, without
addition, deletion, or alteration
except as directed, as your results may be evaluated against expected
results generated using this exact
data set.
Narrative/Case Study
For this lab, you will be creating SQL statements to build a series of
relational tables, using SQL CREATE
statements in a script file format for the Student Database. You will
then populate those tables through
the use of INSERT statements with sample data.
You will need to create a script file and name it YourName_Lab3.txt
containing the following code.
1. The drop table statements listed later in the specifications of this lab.
2. The CREATE TABLE statements required to build the six tables.
3. The INSERT statements necessary to insert all of the sample data.
4. Six select statements to verify that the data is in the tables and
accessible.
To help you accomplish this task successfully, you are being supplied
with the ERD Diagram which
follows, and the exact data to be inserted into each table, which may be
found via the Doc Sharing tab

on the course website.
The following guidelines are being provided to help assist you in
creating your script file.
· Use the names for the tables and columns as listed in the ERD. Do
not change them as it will
affect your grade.
· Creating Constraints
o Create all NOT NULL constraints as indicated in the ERD.
o Create all PK constraints as indicated in the ERD.
o Create all FK constraints as indicated in the ERD.
· Create all of the tables and all of the constraints before populating
any of the tables with data.
· Because FK constraints will be in place when the insert statements
are executed, you will need
to consider carefully which tables must be created before others in
order to ensure that FK
constraints are not violated.
· The COURSE table has a self-referencing FK constraint.
Specifically, some courses have
prerequisite courses. Consequently, the record for a course possessing
a prerequisite course
cannot be successfully inserted into the table unless the record for the
prerequisite course has

already been inserted. This may require you to reorder the insert
statements to resolve FK
violations when loading the table. You may reorder the data provided
for this table, but do not
alter it.
· The data for one table intentionally contains a record containing an
FK constraint that is not
resolved by a record in the parent table. This orphaned record has
been included as an exercise
for you to find. Because this record has an unreconciled FK
constraint, it cannot be successfully
inserted. You will need to delete or comment out the insert statement
for this one record in
order to produce a script that runs without errors.
· Aside from reordering the data for the COURSE table as necessary,
and commenting
out/deleting the ONE record whose FK dependency cannot be resolved
by the data provided,
you are NOT to modify, add to, or delete from the data provided. Your
SQL script must produce
tables containing data identical to the expected solution set, or points
will be deducted.
· ALL character strings must be enclosed in single quotes. This
includes alpha strings and

alphanumeric (remember that any formatting within a numeric string
makes it alphanumeric).
· If you are inserting a NULL, do not enclose the word NULL in single
quotes, as this will insert the
word NULL into the row. To insert a null you simply use the word
NULL.
Deliverables
The deliverable for this lab will include the following documents.
1. Your script file. Create this file in Notepad, or another PURE TEXT
editor—NOT Word. Make sure
your name is in a comment area at the top of the script file. Use a
double dash to create a one-
line comment.
–Jane Smith
–Lab 3
2. Your script file must execute without error. It is recommended that
you begin early in the week,
and post any questions to the Q & A discussion in order to produce a
working script by the due
date.
Be sure your name is on all documents and that all documents have
been included in a single zip file for
this week’s assignments.

Refer to the following ERD in constructing your solution.

PK,FK2Student_ID
Enroll_Date
Final_Grade
LAB STEPS
STEP 1: The DROP Statements
A DROP TABLE statement must appear in your script file, prior to the
SQL statements for creating

the table in question. This will allow you to run and re-run your script
file as often as you need to. The
very first time you run your script the table does not exist, so the IF
EXISTS clause causes the statement
to be ignored. Thereafter, the table will be deleted, ensuring that your
CREATE TABLE statement creates
the table fresh and clean, with only the attributes present in the
current revision of the CREATE
statement. Here is an example of one of the six DROP TABLE
statements you will need to create.
DROP TABLE IF EXISTS `ENROLLMENT` ;
STEP 2: The CREATE TABLE Statements
Next, define the CREATE TABLE statements for the six tables that
you are to create based upon the
ERD (provided above) for this lab. Be sure to follow the guidelines
given above on how and where to
create the different types of constraints for each table. This will
include PK, FK, and NOT NULL
constraints.
STEP 3: The INSERT Statements for the Data
The third step is to create the insert statements to insert the sample
data into the tables created in
Step 2. The data for each table is contained in text files, named for the
table whose data it contains.

Modify the format of the data (e.g., date formats and add or eliminate
quote marks) as needed to craft
your insert statements, but do not change the inherent value of the
data.
STEP 4: The SELECT Statements
The next step of the lab will be to create the select statements to verify
the data was inserted
correctly. You should have six select statements; one for each table.
The command is SELECT * FROM
Table_Name; For example, to select all columns from the Student
table, the command would be
SELECT * FROM student;
Be sure to save all of the above statements in your script file.
STEP 5: Testing and Verifying Your Script
Now we come to the point of verifying that your script file works by
creating all of the tables and
inserting and selecting all of the data. Your script should execute
without errors, and select the entire
contents of each table in turn. Inspect your query results to ensure that
each column and row from
each of the tables is as expected. Correct and repeat testing of your
script until no errors occur, and the
results match expectations. You may also use the DESCRIBE
command to display the table structure of

each table, and verify that PK and NULL constraints have been
properly created. The SHOW CREATE
TABLE statement is useful for displaying the SQL that would
regenerate a given table, which is a useful
way for checking that FKs have been properly created.
Examples:
DESCRIBE STUDENT;
SHOW CREATE TABLE STUDENT;

CIS 336 iLab 4 Introduction to Select, Insert, Update, and
Delete Statements (only SQL Command, No output)
www.cis336study.com
CIS336: Lab 4: Introduction to Select, Insert, Update, and Delete
Statements
LAB OVERVIEW

Lab 4 will introduce the various aspects of the SQL select statement
and the methods of retrieving data from the database tables. This lab
will also introduce the fundamentals of updating and deleting records.
This lab may be completed using either DeVry’sOmnymbus EDUPE-
APP lab environment, or a local copy of the MySQL database running
on your own computer using the OM database tables. The lab will
utilize a set of tables that are represented by the ERD (OM_ERD.docx)
and are created and populated by the script file (create_OM_db.sql).
Follow the instructions in the file CreateOMTables.docx to create your
database, tables, and data.
A few IMPORTANT things to note if using EDUPE MySQL:
**There can be NO SPACES in alias names given to a column. For
example:
Select unit_price as “Retail Price “ from items; –this does NOT work
in EDUPE MySQL.
Any of the following WILL WORK:
Select unit_price as “RetailPrice” from items;
Select unit_price as “Retail_Price” from items;
Select unit_price as Retail_Price from items;
Select unit_price as RetailPrice from items;
**Any calculated fields MUST be given an alias (and note above NO
SPACES in alias). For example:
select unit_price * 2 from items; –this does NOT work in EDUPE
MySQL
This will work:

select unit_price * 2 as NewPrice from items;
Deliverables

customer first name, last name, and phone number. Sort the results by
customer last name, then first name.
2. Write a query that displays each customer name as a single field in
the format “firstnamelastname” with a heading of Customer, along
with their phone number with a heading of Phone. Use the IN
operator to only display customers in New York, New Jersey, or
Washington D.C. Sort the results by phone number.
3. Write a query that will list all the cities that have customers with a
heading of Cities. Only list each city once (no duplicates) and sort in
descending alphabetical order.
4. Write a query that displays the title of each item along with the price
(with a heading of Original) and a calculated field reflecting the price
with a 25% discount (with a heading of Sale). Display the sale price
with two decimal places using the ROUND function. Sort by price
from lowest to highest.
5. Write a query that displays the customer_first_name,
customer_last_name, and customer_city from the customers table. Use
the LIKE operator to only display customers that reside in any zipcode
beginning with 4.

6. Write a query that displays the order id and order date for any
orders placed from March 1, 2014 through April 30, 2014. Do this
WITHOUT using the BETWEEN clause. Format the date field as
Month dd, yyyy and use a heading of “Ordered”.
7. Write a query that displays the order id and order date for any
orders placed during the month of May, 2014. Do this using the
BETWEEN clause. Format the date field as mm/dd/yy and use a
heading of “Ordered”.
8. Write a query which displays the order id, customer id, and the
number of days between the order date and the ship date (use the
DATEDIFF function). Name this column “Days” and sort by highest
to lowest number of days. Only display orders where this result is 15
days or more.
9. Write a query which displays the order id, customer id and order
date for all orders that have NOT been shipped, sorted by order date
with the most recent order at the top.
10. The Marketing Department has requested a new report of shipped
orders for which the order was placed on either a Saturday or a
Sunday. Write a query which displays the order id, order date, shipped
date, along with a calculated column labeled “Order_Day” showing
the day of the week the order was placed (use the DAYNAME
function). Only display orders that have shipped and were placed on a
Saturday or Sunday. Sort by order date with most recent orders at the
top.
11. Write a query to display the customer last name, phone number,
and fax number but only display those customers that have a fax
number.

12. Create a statement to insert a new record into the items table with
the following values:
item_id: 11
title: Ode To My ERD
Artist_id: 15
unit_price: 12.95
Show your INSERT statement along with the results of the following
SELECT query to verify that the insert worked correctly.
select * from items where item_id> 10;
13. Create a statement to update the record inserted in the previous
step to change the unit price of this item to 7.95.
item_id: 11
title: Ode To My ERD
artist: 15
unit_price: 7.95
Show your UPDATE statement along with the results of the following
14. Create a statement to delete the entire record that was inserted and
then updated in the previous steps.
Show your DELETE statement along with the results of the following

15. Using the SUBSTRING and CONCAT functions, write a query to
display each customer name as a single field in the format “Jones,
Tom” with a heading of Customer along with the customer_phone
field in a nicely formatted calculated column named Phone. For
example, a record containing the customer_phone value 6145535443
would be output with parentheses, spaces, and hyphens, like this: (614)
555-5443.Sort by last name.
This is the end of Lab 4.

CIS336: Lab5: Joining Tables
LAB OVERVIEW
Lab 5 will introduce the concept of multi-table JOINS in order to work
with data in two or more related tables simultaneously. This lab may
be completed using either DeVry’sOmnymbus EDUPE-APP lab
environment, or a local copy of the MySQL database running on your
own computer using the OM database tables. The lab will utilize a set

of tables that are represented by the ERD (OM_ERD.docx) and are
created and populated by the script file (create_OM_db.sql). Follow
the instructions in the file CreateOMTables.docx to create your
database, tables, and data.

This will work:
Deliverables

LAB STEPS: Complete each of the exercises below:
1. Use the JOIN ON syntax to write a query to display the order id,
order date, customer name formatted as a single field (i.e. “Tom
Jones”) with a heading of Customer, and customer_city for customers
residing in the state of OHIO. Sort the output to display the newest
orders first.
2. Use the JOIN USING syntax to display the order_id, order date, and
shipdate for orders to Karina Lacy that have shipped.
3. Use the implicit join syntax (the WHERE clause) to display the last
name, city, order date and ship date for all orders shipped in 2012.

the table may be joined to itself using these two attributes
(employee_id, manager_id). This is known as a SELF-JOIN. Use a
SELF-JOIN on the employees table to produce a result containing two
columns: the concatenated last_name and first_name of the manager,

CIS-336: Lab7: Working with Views
LAB OVERVIEW
Lab 7 will introduce the concept of database views. This lab
may be completed using either DeVry’sOmnymbus EDUPE-
APP lab environment, or a local copy of the MySQL
database running on your own computer using the OM
database tables. The lab will utilize a set of tables that are
represented by the ERD (OM_ERD.docx) and are created
and populated by the script file (create_OM_db.sql). Follow
the instructions in the file CreateOMTables.docx to create
your database, tables, and data.
A few IMPORTANT things to note if using EDUPE
MySQL:

**There can be NO SPACES in alias names given to a
column. For example:
Select unit_price as “Retail Price “ from items; –this does
NOT work in EDUPE MySQL.
**Any calculated fields MUST be given an alias (and note
above NO SPACES in alias). For example:
select unit_price * 2 from items; –this does NOT work in
EDUPE MySQL
This will work:
Deliverables
• Lab Report (Answer Sheet) containing both the student-
created SQL command(s) for each exercise, and the output
showing the results obtained. Be sure your name is on the
file.

1. Use an ALTER TABLE statement to update the
customers table so that the Primary Key field is an auto-
increment field, then create TWO insert statements to test
proper operation, using your own first and last name for one
(and a name of your choice for the second one), and any data
you care to imagine for the remaining fields.
IMPORTANT NOTE: When using a LOCAL copy of
MySQL, if you attempt to simply issue the ALTER TABLE
command you have composed by itself, you should receive
an error similar to the following (try it for yourself!).
ERROR 1833: Cannot change column ‘customer_id’: used
in a foreign key constraint ‘orders_fk_customers’ of table
‘om.orders’
(Note – EDUPE will not give this error message, however
you should still follow the CORRECT procedure as
discussed here to complete this problem).
The reason for this is that you are attempting to alter data in
one column that has a defined PK:FK relationship to a field
in another table. Referential Integrity rules prevent this. So,
how do you resolve such a problem?
One approach to solving this dilemma is to turn off the
foreign key checks that implement referential integrity rules.
However, the danger here is that other users and processes
operating on the database while these constraints are
suspended could create or modify data in a way that

compromises integrity. We can solve this second problem by
preventing other users and processes from altering the data
in the table in which we are working until we have turned
the foreign key checks back on. We therefore need to
construct a script that does the following.
a) Locks the customer table – lock table customers write;
b) Turns off FK checks – set foreign_key_checks = 0;
c) Alters the table to add the auto_increment feature to the
PK field
d) Turns FK checks back on – set foreign_key_checks = 1;
e) Unlocks the customer table – unlock tables;
It is VERY important to consider that altering tables can
require a bit of time for very large tables, and that while the
table is locked, other users and processes cannot operate.
Consequently, this kind of modification should not be done
during peak operating hours in a production operation (as a
student in a lab exercise, working on your own database, you
may do this at any time) but ideally in hours during which
the business does not normally operate. In cases where
round-the-clock, high availability of a database is required,
other approaches may be required. Addressing this problem
in a high-availability, high-demand environment is an
advanced topic, study of which is outside the scope of this
course. Use the outline below to construct your script. Show

all commands in your answer sheet along with the output of
the commands.
lock table customers write;
set foreign_key_checks = 0;
– Replace this comment with your ALTER TABLE
command to add the auto_increment feature to the PK field
set foreign_key_checks = 1;
unlock tables;
–statements to insert two rows into the table
–verify auto_increment with a select statement
2. The Vice President of Marketing for your firm wants the
firm’s sales representatives to be able to directly view and
edit customer details, but only for the state to which a
particular sales representative is assigned. You have
suggested that this need can be addressed with a view. For
example, a view could be created for one particular state,
and user account permissions for accessing that view
granted only to sales representatives from that state. The VP
has asked you to quickly create a simple proof-of-concept
demonstrating how this might work. Complete the following
steps:

a. Construct a view on the customers table called
CA_CUSTOMERS that consists of all data about customers
that live in California.
b. Display the data using this view to verify that only
customers that reside in California are visible.
c. Prove that It is possible to add or update records through
this view by updating the record for Karina Lacy to change
the spelling of Karina’s last name to Lacie.
d. Display the data using the customer table to verify that
the change has been made.
Show all commands in your answer sheet along with the
output of the commands.
3. The Senior Customer Service Manager has requested the
ability to create a report at any time that will show shipped
orders that took some specified number of days to fulfill.
a. Create a view named SHIPPING_TIME that lists only
customer_first_name, customer_last_name, order_date,
shipped_date, and the calculated field days_to_fulfill (use
the DATEDIFF function) showing the number of days
between when the customer placed the order and when it
was shipped. Show the data from this view.
Now let’s do some queries by adding sorting and filters
USING THIS VIEW, WITHOUT CHANGING IT.

b. Use the view to display the data sorted by highest to
lowest days to ship
c. Use the view to display only the orders that took less than
10 days to ship.
d. Use the view to display only the orders that took more
than 30 days to ship.
4. Queries that require joins and aggregate functions can be
easier to construct when using a view as a “temporary”
table. Consider a report to show total sales by artist.
a. First create a view called SalesData that displays the
order_id, item_id, the calculated field ItemTotal (which is
quantity times price), the title and artist_id.
b. Display the data in the SalesData view sorted by artist_id.
Does this help you to “visualize” how to group the data to
create the totals?
c. Create a query USING THIS VIEW and the appropriate
aggregate function to display artist_id and the total sales for
each artist.
d. Now join to the artist table in order to display the
artist_name along with the total sales.
5. Now use this same method to display the total sales per
customer.

a. Create a view called SalesData with the appropriate data.
At a minimum you will need customer_id and the calculated
item total. DO NOT use the customer table in this view, it
will be joined later.
b. Display the data in your view sorted by customer_id. Does
this help you to “visualize” how to group the data to create
the totals?
c. Create a query USING THIS VIEW and the appropriate
aggregate function to display customer_id and the total sales
for each customer.
d. Now join to the customer table in order to display the
customer_name as a single field named Customer along with
the total sales. Sort the report by Total sales in descending
order.
