With SQL you can answer questions using a database, the ultimate system of record for most organizations. As nearly every industry is moving toward being more data-driven, having this skill will give you a larger role in decision-making wherever you work.
This course will teach you how to explore, modify and export data from a database. You’ll be introduced to foundational concepts like tables, data types, and queries. Once you understand the basics of viewing tables, you’ll be introduced to more advanced querying techniques like filtering and aggregating. You will be able to drill down into specific cases or step back and see larger patterns.
You’ll also learn how to combine information from different tables using join statements and views. The final day of the course will cover advanced techniques like creating subqueries and stored procedures.
This course will use Postgres, an advanced open-source database. Concepts from this course will apply equally to other databases such as MySQL and SQL Server, with the minor syntax differences noted during class.
