Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.

Question

1. Create a data model from the below and ensure it show:

a.) Attributes

b.) Entities

c.) relationships

2. Draw the data model cardinality table.

“Martial Arts R Us” (MARU) needs a database. MARU is a martial arts school with hundreds of students. The database must keep track of all the classes that are offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance. 1.Create a complete Crow’s Foot ERD for these requirements: 2.Create a relational diagram for the data model. 3.Draw the dependency diagram showing partial and transitive dependency(if any). 4. Normalize the tables to 3NF. 5. Show the dependency diagram after normalization. 6. Use SQL to create all tables in Access. Do not forget FK,PK 7. Create relationships.
