Experience Gained from this Assignment
The assignment has enhanced my greater understanding on the method to use IBM DB2 Express to develop database. Although, it takes me several hours to download the software; however; I have learned several techniques to develop the database. Although, I have already developed the method to create database from the classroom note, however, the IBM DB2 Express has improved my understanding on the method to use the software to develop a database table. In addition, the assignment has developed my knowledge on the database normalization. Through normalization process, I have been able to improve the functionality of the table. While this assignment has improved my knowledge on the database development, there are still some challenges faced in the assignment; first, it took me some time to write the SQL code to create the table. Essentially, thorough understanding of SQL is very important in the database, and understanding of SQL is very important in this assignment.
PART 4 OF THE ASSIGNMENT
Normalization is the process of simplifying database in the normal form to give the database optimal structure. The normal form should be in a linear progression of a rule where higher normal form achieves better and more efficient form. Normalization theory reveals normal forms as follows:
1. First Normal Form (INF)
2. Second Normal Form (2NF)
3. Third Normal Form (3NF)
4. Boyce Codd Normal Form
5. Fourth Normal Form
6. Fifth Normal Form
The student database has met First Normal Form (INF) normalization requirements based on the following reasons:
First Normal Form (INF) reveals that all column values in the database must be atomic. The INF dictates that for every row-by-column in a given table, there should be only one value and not list of value or array of value. The benefit of this rule is that if all the list of values is stored in a single form, there is no way to retrieve data from the database, and there is no way to manipulate those values. The Student Table does not violate INF rules because the lists of values are stored in a separate column. Typically, the data stored in the Student Table are atomic because it is easy to retrieve information from the table, and it is easy to create report from the table. While INF prohibits the presence of repetition, the Student Table satisfies the requirements of the INF because the table stores single item columns in separate column.
Second Normal Form (2NF)
A table is in Second Normal Form (2NF) if it has satisfied the requirement of INF and if its non-key column is fully dependent on the entire primary key. Similarly, "tables should only store data related to one entity and the entity should be described by its primary key. In addition a table is said to be in Third Normal Form (3NF), if it is in 2NF and if all non-key columns are mutually independent." (Litwin, Getz & Gunderloy, 2002 P. 13)." Based on the rules of the 2NF and 3NF, it is critical to redesign a new table to satisfy the Second Normal Form and Third Normal Form requirements. The new tables are created to meet normalization standard and the tables are created using SQL in DBMS.

Thus, the above table has satisfied requirements of First Normal Form (1NF) and Second Normal Form (2NF). However, they have not yet satisfied the Third Normal Form (3NF). To ensure that all the tables meet the normalization process and satisfy the 3NF, the table must be mutually independent. (Johnson, 2011).
