DevOps engineers commonly have a need to access data stored in database systems. SQL is a standard for communicating with database systems that a DevOps engineer will encounter in their day-to-day lives.

Go provides a standard library for interacting with SQL-based systems called database/sql. The interfaces provided by that package, with the addition of a database driver, allow a user to work with several different SQL databases. In this lesson, we’ll look at how we can access a Postgres database to perform basic SQL operations using Go.
