This chapter provides a brief introduction to working with relational databases in a marketing context. You'll learn about their structure, how to talk about them using database lingo, and how to begin an analysis by using simple SQL commands to select and summarize columns from database tables.
In this chapter, you'll learn how to filter tables for rows that satisfy your criteria of interest with the help of basic comparison operators and combinations of multiple criteria.
Besides selecting columns and filtering rows, there is much more that you can do with SQL! This chapter will present you with some examples that will motivate you to continue to develop this newly gained skill!
