Assignment Brief:
Some of the most difficult decisions that you face as a database developer are what tables to
create and what columns to place in each table, as well as how to relate the tables that you
create. Normalization is the process of applying a series of rules to ensure that your database
achieves optimal structure. Normal forms are a progression of these rules. Each successive
normal form achieves a better database design than the previous form did. Based on your
understanding for the various normal form respond to the following problems and provide the
optimal answer/solution.
Problem#1: 1st Normal Form (1NF)
