Databases & SQL

SQL

Almost every application on earth stores its data in a database, and SQL is how you talk to it. This course takes you from writing simple queries to joining data across tables, grouping and aggregating for real reports, and designing schemas that stay fast as they grow. You finish able to pull exactly the data anyone asks for.

Overview

What this course is about

SQL is taught here as a hands-on, live one-on-one course rather than a stack of videos. Almost every application stores its data in a database, so being fluent in querying and designing one is a foundational skill across tech.

You will use indexes to speed things up and design normalised schemas, guided by an instructor who has done this work professionally.

Because it’s taught live and personally, questions get answered the moment they come up.

By the end

What you’ll be able to do

  • Write queries from simple SELECTs to multi-table joins
  • Design normalised schemas
  • Use indexes to speed things up
  • Work with stored procedures and transactions
