Database Indexing and Performance: Mastering B-Trees and B+ Trees

How do databases find a single record among millions in milliseconds? The secret lies in indexing, a crucial skill for any developer or database administrator. This text-based course guides you from the absolute basics of database storage to the inner workings of index structures, helping you write faster queries and design efficient databases. What you will learn: Learn the core principles of database storage and why indexing is essential for performance; Understand the structural differences between B-Trees and B+ Trees and how they manage disk I/O; Create and configure single-column, composite, and unique indexes for optimal query execution; Analyze execution plans to identify slow queries and determine when to use or avoid indexes; Explore modern indexing strategies, including partial indexes, expression indexes, and LSM-tree concepts used in modern distributed databases. You will start with foundational database storage concepts before diving deep into tree-based data structures, practical indexing patterns, and real-world performance tuning through written explanations and code-based scenarios. This course is perfect for beginner developers, aspiring database administrators, and system designers who want to understand database internals with no prior experience required.
