Database Normalization

Submit dependency diagrams for all entities you create. The following table is a sample of data, before ORDERS was normalized. Please start with the below table and then write out each dependency diagram as you move from 1NF to 2NF to 3NF. You must show your progress and submit your final document with all dependency diagrams.
