CIS 336 Group Project
www.newtonhelp.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
yourname_reports.docx to show the result of each query. For the
update and each report,
· describe the update and report requirement;
· show the query; and

· show the result of the query.
Include a final section for Conclusions and Lessons Learned
regarding the project.Note that your deliverables each week include

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.newtonhelp.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

CIS 336 iLab 3 Building the Physical
www.newtonhelp.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.newtonhelp.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;

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,

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.

An employee may be managed by another employee. To denote an
employee’s manager, the employee_id of the manager is entered into
the manager_id field of the employee reporting to that manager. In
order to produce a list of which managers supervise which employees,
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 iLab 6 Group Functions and Subqueries
www.newtonhelp.com
CIS336: Lab 6: Group Functions and Subqueries
LAB OVERVIEW
Lab 6 will introduce the concept of group functions and subqueries to
meet more complex report requirements. 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.
example:
in EDUPE MySQL.

MySQL
This will work:
Deliverables
1. Write a query to determine the total number of items on each order.
Display the order_id and the total with a heading of TotalItems (note
no spaces). Filter to only display information for order_id of 600 or
higher.
2. Re-do query 1 but filter to only show those orders with more than 2
items ordered. Sort by the number of items ordered, lowest to highest.
3. The order_details table has a quantity for each item ordered. Show
the total amount charged for each item on the order (quantity times
price). Display order_id, the item id, the unit price, the quantity times
price of the item labeled as “Itemtotal” (note NO spaces). Sort by
order id and filter to only display those order ids between 400 and
700.

4. Write a query to display the total amount for each order: show the
order id and total. Sort by descending order on the total and only
display orders with a total of $40 or more.
5. Re-do query 4 but show the customer name for each order
(formatted as a single field with heading of Customer) along with the
city, order id and total. Filter to only display customers that live in
California. Sort by city.
6. Display the total amount of sales per item. Show title, total quantity
sold with a heading of Quantity, total sales with a heading of
“TotalSales” (not NO space). Sort by highest to lowest total.
7. Display the total sales for each customer: show customer name (as
single field) with a heading of Cutomer and total. Sort lowest to
highest total. Filter to only display customers with $50 or more in
total orders.
8. Use subqueries to determine which (artist) had the item ordered in
highest quantity on an order? First determine the highest quantity on
any order, then determine the item number associated with it, then
display the artist.
9. Display the total sales by artist: show artist name, total. Sort highest
to lowest.
10. USE A SUBQUERY to Increase price of all items by ‘No Rest for
the Weary’ by 10%. If working in MySQl you will need to disable
safe mode. Show prices before and after. Rollback after.
11. USE A SUBQUERY to display names of customers that have
unshipped orders.

CIS 336 iLab7 Working with Views
www.newtonhelp.com
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.
example:
in EDUPE MySQL.

MySQL
This will work:
Deliverables
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.
