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:

 

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 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 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.

Assignment 6: SQL Concepts and Database Design

Due Week 7 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 work for a finance industry-based organization. Your organization is looking to submit its database design documentation to an evaluation team in order to meet Sarbanes-Oxley (SOX) compliance. You have been assigned to assist in preparing the documentation of the organization’s sales database. You are asked to propose a data dictionary that can be used to document the following:

• Employee (EmpNumber, EmpFirstName, EmpLastName, CommissionRate, YrlySalary, DepartmentID, JobID)

• Invoice (InvNumber, InvDate, EmpNumber, InvAmount, CustomerID)

• InvoiceLine (InvLineNumber, InvNumber, ProductNumber, Quantity)

• Product (ProductNumber, ProductDescription, ProductCost)

• Department (DepartmentID, DepartmentDescription)

• Job (JobID, JobDescription)

• Customer (CustomerID, CustomerName, CustomerAddress, CustomerPhone)

Write a three to four (3-4) page paper in which you:

1. Create a data dictionary that includes the following:

1. A description of the content for each field

2. The data type of each field

3. The format the data will be stored as in the field

4. The range of value for the field

5. A label, as required, if the attribute is a primary key or foreign key

Note: An example is shown in Table 7.3 in chapter 7 of the textbook.

2. Imagine that you are asked to identify the number of days that exist between the first invoice and last invoice for each month and complete the following:

1. Construct a query that will show the number of days that exist between the first invoice and last invoice, for each month, for each employee, using the DATEDIFF function. Be sure to provide the SQL script that will carry out this function.

2. Construct a query to show the expected payment date if invoices are due within 30 days of transaction.

3. Construct a query that will show distinct area codes of the customers.

3. Create a plan of the necessary activities that would be required to implement a valid database design process by including the following:

1. Steps in the conceptual design stage

2. Steps in DBMS selection stage

3. Steps in logical design stage

4. Steps in physical design stage

5. Task details of each activity within each stage
