What this resource explores
An introduction to relational databases using SQL. Topics connect queries and table relationships with schema design, data changes, views, indexes and database scaling.

- Views, indexes and database scaling
Who it is for
Learners interested in storing, querying and organizing structured data, before, alongside or after a broader computer-science introduction.
Background & preparation
The provider allows this course before, during or after CS50x. Its focus is databases rather than a complete introduction to computer science.
A way to approach it
Follow queries and relationships before schema design and updates, then connect views and indexes to the questions they address. Use the provider’s problem sets for practice.
