Database Management & Normalization

Hello, 
These are the written questions for my assignment. I understand that question one is more opinion based but do respond to the best of your        ability. I have also attached the rubric to the assignment so please type out the answers to each question adequate to their points worthiness.    Please also find attached the book that we use in the course: ISBN: 9780134773650 

The questions are as follows: 

1) Why are we talking about database management and what are the benefits of taking this course (enterprise data management)?
2) Whats included when we say database management?
3) Why would businesses want their employees knowing about database management even if you are not in Information Technology?
4) Explain data normalization (in your own wordsbut cite sources!), why its important and the steps involved.

Thank you so much for your help
