Master Relational Databases with MariaDB

MariaDB Fundamentals: Understanding Relational Databases with MariaDB is a practical, beginner-friendly guide designed to help you understand how modern relational databases work—and how to use MariaDB effectively in real-world projects.

Databases sit at the heart of nearly every modern application. From websites and business systems to analytics platforms and cloud services, structured data storage is a critical skill for developers, analysts, and IT professionals. MariaDB has emerged as one of the most trusted and widely adopted open-source database systems, offering MySQL compatibility, enterprise-grade performance, and a strong community-driven future.
