SQL For Beginners

A lot of folks get into SQL and databases from the programming side and pick things up slowly from context. Here, I’ll go into some of what SQL relational databases are like, how indexes and unique keys work, best practices for designing tables for your modules and data, and how to best design queries so they are as fast at 20,000 nodes as they are at 20. The topic will focus mostly on mySQL, but will be generally applicable to all relational databases.
