I have always loved designing databases. A well designed database is just a beautiful thing. Queries work faster, the data integrity is maintained and the storage is optimized.
This post is a good starting point for those who would like to learn database design. One of my favorite books is “Database Design for Mere Mortals” by Michael J. Hernandez.

Wow Barry, this is pretty amazing. I’ve been reading normalization rules all morning, and your article makes it simple. I work with a young adult leadership development team and one of our tasks is to create a new database to track the attendance of a popular area youth outreach program… and I’ve been scratching my head for two days trying to figure out what data to store in separate tables, and what do keep with the student records. Should the parent’s names be stored together, separate, first and last, or combined, and in the student table, or in a separate table. Two kids could have the same parents. But two kids could have the same dad, but two different moms and two addresses… In the case of a divorced family where we want to send a letter to the parents… it make’s my brain hurt to think about it. So I could just make the kid pick one address to use as their primary address… or I could Rel-table it and let them have as many parents and addresses as they want… because the next fun thing is emergency contact people. Ah the joys of data management. Our Master’s Commission students are really going to enjoy your information as we design this database. Thanks… you’re helping us teach valuable leadership skills to the next generation.

I’m not even going to pretend I know about this stuff here. My head is hurting just from looking at it. I rather hire a designer to do the work for me

anyhow, maybe you can say something about the situations when one should not use normalized form. facebook for example doesn’t use normal form. nor does youtube. nor stumbleupon as judged by some discrepancy in statistics of reviews etc…

for example, when one needs to have various statistics, it is very expensive to do selects and counts each time in real time…
