The Strayer Oracle Server may be used to test and

2. compile the SQL Queries developed for this
assignment. Your instructor will provide you with
login credentials to a Strayer University
maintained Oracle server.
Imagine that you have been hired as a consultant
to assist in streamlining the data processing of an
international based organization that sells high-
end electronics. The organization has various
departments such as payroll, human resources,
finance, marketing, sales, and operations. The
sales department is the only department where
employees are paid a commission in addition to
their yearly salary and benefits. All other
departments compensate their employees with a
yearly salary and benefits only. Commission is
paid by multiplying the employee’s commission
rate by the total amount of product units sold. You
have access to the following data sets:
Employee (EmpNumber, EmpFirstName,
EmpLastName, CommissionRate, YrlySalary,
DepartmentID, JobID)
Invoice (InvNumber, InvDate, EmpNumber,
InvAmount)
InvoiceLine (InvLineNumber, InvNumber,
ProductNumber, Quantity)

3. Product (ProductNumber, ProductDescription,
ProductCost)
Department (DepartmentID,
DepartmentDescription)
Job (JobID, JobDescription)
Write a two to three (2-3) page paper in which
you:
Design a query that will allow the finance
department to determine the commissions paid to
specific employees of the sales department for the
month of December. Note: You will need to
generate the tables described above (Employee,
Invoice, InvoiceLine, Product, Department, and
Job) in order to compare and validate your code.
Validated query code must be part of your paper.
Compare the code of the query you designed in
Question one (1) to one that would show how
much total compensation is paid to each employee
for the same month.
Determine and explain the factors necessary to
ensure referential integrity.
Create an object-oriented model to show how the
tables are interrelated through the use of
graphical tools such as Microsoft Visio, or an open
source alternative such as Dia. Make sure that you
are able to show the relationship types such as

4. 1:M, 1:1, or M:1. Additionally, remember to include
the determined factors from the previous
assignment requirement. Note: The graphically
depicted solution is not included in the required
page length.
Identify which data components are the entities
and attributes, and the relationship between each
using an object representation diagram through
the use of graphical tools such as Microsoft Visio,
or an open source alternative such as Dia. Note:
The graphically depicted solution is not included
in the required page length.
Describe how Big Data could be used to assist in
the productivity and forecasting of the
organization’s products and resources.
Your assignment must follow these formatting
requirements:
Be typed, double spaced, using Times New Roman
font (size 12), with one-inch margins on all sides;
citations and references must follow APA or
school-specific format. Check with your professor
for any additional instructions.
Include a cover page containing the title of the
assignment, the student’s name, the professor’s
name, the course title, and the date. The cover
page and the reference page are not included in

5. the required assignment page length.
Include charts or diagrams created in Excel, Visio,
MS Project, or one of their equivalents such as
Open Project, Dia, and OpenOffice. The completed
diagrams / charts must be imported into the Word
document before the paper is submitted.
The specific course learning outcomes associated
with this assignment are:
Describe the role of databases and database
management systems in managing organizational
data and information.
Design and implement a database solution to solve
a proposed business problem.
Use technology and information resources to
research issues in the strategic implications and
management of database systems.
Write clearly and concisely about topics related to
the strategic planning for database systems using
proper writing mechanics and technical style
conventions.
