Hello, 

I need help with this. Please review thoroughly before accepting the bid. I will be checking for plagiarism!

Thanks 🙂

Part 1:

 Prior to beginning work on this interactive assignment, read chapter 6 of your textbook as well as the Absolute Beginner’s Guide to Database Normalization (Links to an external site.), Database Normalization (Links to an external site.) and Normalization: How far is far enough (Links to an external site.) online resources, and review any relevant information in this week’s lecture.

Normalization is an important step towards translating models and diagrams into relational databases. In this exercise, you will need to normalize the Grade_Report table below and explain the steps needed to do so.

For this assessment, consider the following entity and its attributes and normalize the entity Grade_Report to 3NF.

Entity: Grade_Report (StudentID, StudentName, Phone, DOB, Address, Email_Address, CourseNumber, CourseName, Grade, DepartmentID, DepartmentName)

Explain the steps needed to normalize this entity to 1NF, 2NF and 3NF. List the resultant Normalized entities in the same format as the original Grade_Report.

Once the entity is normalized to 3NF, describe any issues this entity might have that can be solved by normalization. Explain the functional dependencies that exist between the attributes. Provide the steps required to break up the Grade_Report entity into multiple entities that each have a single theme.

minimum of 250 words.

Part 2:

 

The Normalization Process: Converting the ERD

Prior to beginning work on this assignment review Chapter 6 in your textbook, read the Absolute Beginner’s Guide to Database Normalization (Links to an external site.) and Database Normalization (Links to an external site.) online resources, and review any relevant information in this week’s lecture. These sources will be used to support your work in the assignment.

You developed and revised your ERD in Week Two, bringing you one step closer to creating the physical database in the Structured Query Language (SQL) server in your virtual lab environment. However, before doing so, you need to check the conceptual model you created and ensure that it meets the First, Second and Third normal forms.

For this assignment, explain the purpose of the normalization process including a description for each of the five normal forms (1NF, 2NF, 3NF, 4NF, and 5NF) and providing examples for each. Cite the sources for all examples. You will then translate the ERD model you created and revised in Week Two into 3NF.

Within your paper explain how each table in your ERD meets 1NF, 2NF, and 3NF. If the tables do not meet the forms, you need to resolve any issues and normalize the database in order to meet 1NF, 2NF, 3NF. If issues were encountered and had to be resolved, describe the rules that were violated and how you resolved them.
