This week we learned about data modeling and proposed a simple database based on our previously created XML document. I really enjoyed learning about this; I felt that the basic concepts were accessible and very immediately useful. I had learned a little bit about entity relationship diagrams in IRLS 515, but felt that I was able to get a deeper understanding of it this time around.
I felt that I gained a good understanding of the crow's foot notation after spending some time on it, as well as a pretty good understanding of the differences between entities and attributes. The thing I am still having a hard time with is how everything goes together in the diagram when you have several or many entities/attributes. I also was only able to grasp a basic understanding of database normalization. I really look forward to learning more about this topic; I have a small business of my own that I would like to create a database for, so that gives me extra motivation to try to understand these topics.
