Before you do this assignment you should review the google slides on Relational Design and normalization and watch the video on creating the ERD for the co-op. I intend to provide extensive feedback when I grade these, because these are important and core concepts in developing databases.
Consider the following table of sample data:
Student ID | Name | Major | Department | Department Bld | DeparmentRoom | Courses and grades | Advisor | advisor phone | |
123 | Jill Henry | JH@central.edu | Programming | IT | BE | 3176 | IT 100 -3.5, IT 120-4, IT 110--3.6 | John Smith | 2065551234 |

567 | Joy Lewis | jl@central.edu | Math | MAT | SB | 120 | MAT 100--4, MAT 111 --3.7 | Mark Brown | 2065554567 |
789 | Han Li | HL@central.edu | History | HIS | BE | 222 | ENG 100-3.5, SOC 101 - 2.8, HIS 121--4, MAT 100-3.2, HIS 122-- | Karen Nguyen | 206559876 |

1. Look carefully at the data and describe any violations of the first three normal forms that you see.
2. Use Lucid Charts or Draw IO to create a normalized Entity Relation Diagram based on the data above. Remember Entity relationship Diagrams do not contain any data, just the Entities, their attributes and the relationships. You can do question 1, in a text box on the diagram.
To turn in. provide a link to the diagram on lucid charts (remember to share it) or a picture of the diagram from lucid chart or Draw.io.
