Databases are useful for both storing and using data effectively. Using a relational database serves several purposes.

This lesson will teach you what relational databases are, how you can load data into them and how you can query databases to extract just the information that you need.

Prerequisites

We expect you to have learn a bit about the SAFI dataset in the spreadsheet and OpenRefine session. It is not necessary, but will greatly improve your ability to understand the power of SQL and when to use it versus another tool.
