Assignment: Database Systems and Database Models
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 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 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.
