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: 1* Normal Form (1NF) Consider the Students table, with the primary key underlined, and the following data: Students: Alpha 100111 Name John Doe Email doe@usna.edu Courses NN204, SI204, IT221 SM223, EE301 S1204 GradePoints 2,3,3 092244 Matt Smith Melinda smith@usna.edu black@usna.edu 4,4 113221 Black 090112 Tom Johnson Johnson@usna.ed NN204, SI204, 4,2,3 u IT221 a) Is the Students table in 1NF?
