Database Basics Explained

Description

Databases are explained without assuming any background. Seven PDF lessons start with what a database is and why it matters, then describe relational databases and tables and the basics of SQL for reading and finding data.

You then learn how to create and modify tables, connect data with relationships and keys, and apply design principles that keep a database tidy. The last lesson brings the ideas together in a real-world database project. After reading, you will be able to understand a simple database design and write basic queries. Exercises and tables appear in most lessons.

Who it is for: beginners who work with data or are starting out in tech and want to understand how databases are organized.
