Part 2: Module Practice:

You have been given a file that contains the following fields relating to CD information. Using the steps of normalization, create a logical data model that represents this file in third normal form. The fields include the following:

• Musical group name
• Musicians in group
• Date group was formed
• Group’s agent
• CD title 1
• CD title 2
• CD title 3
• CD 1 length
• CD 2 length
• CD 3 length

The assumptions are as follows:
