MySQL

I feel confident with the mysql command line. I reviewed the required uacbt tutorials and took notes so I feel that I can perform basic operations. However, I have difficulty with the relational database concepts: including entities, attributes, relationships and database normalization. When I began reading the lecture, readings, and tutorials I felt I was gaining some understanding but as I went on reading through more examples I just got confused and stayed confused. For example, the invoice reading began strong for me, then as more and more tables were compiled, I got lost with the normalization. What might help me understand these topics? Well, I think some stripped down between-the-lines explanations would help me. I hope that the database part 2 (retrieval) will help fill in some of the missing gaps in my understanding. Also, as I go through the hands-on exercises and assignments I hope that things will "normalize" :)
