Optimizing SQL Queries With B-tree Indexes And More

Behind the scenes, SQL queries use various data structures to optimize data retrieval, manage storage, and ensure efficient querying. The most common data structures used in relational databases for handling SQL queries are:

B-tree (Balanced Tree)

Usage: B-trees are the most commonly used data structure for indexing, especially for clustered and non-clustered indexes.
How it works: A B-tree is a self-balancing tree structure that keeps data sorted and allows for efficient insertion, deletion, and searching in logarithmic time.
In SQL: When you create an index (e.g., a B-tree index), the data...
