1. Assignment 2: Database Systems and Database Models Due
Week 2 and worth 90 points The Strayer Oracle Server may be
used to test and 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)
•Product (ProductNumber, ProductDescription, ProductCost)
•Department (DepartmentID, DepartmentDescription) •Job
(JobID, JobDescription) Write a two to three (2-3) page paper
in which you: 1.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. 2.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. 3.Determine and explain the factors necessary
to ensure referential integrity. 4.Create an object-oriented
model to show how the tables are interrelated through the use of

2. graphical tools. Make sure that you are able to show the
relationship types such as 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. 5.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. Note: The
graphically depicted solution is not included in the required
page length. 6.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 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. Click here to view the grading rubric.
