Assignment 2 Database Systems and Database Models
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 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.
