When I started writing this blog post, I had titled it “Tips for Designing Databases” and I planned to talk about various database design techniques. However, as I did more and more research, it dawned on me that one of the most crucial, and most overlooked, components of database development, is the selection of data types for columns.
Much of the information presented in this article was taken from presentations by Jay Pipes and a talk by Ronald Bradford. The talks are The Top 20 Design Tips For MySQL Enterprise Data Architects, Join-fu: The Art of SQL Tuning and SQL Query Tuning: The Legend Of Drunken Query Master.
