Database Animations: How Index Seeks Work
Read OriginalThis article by Brent Ozar provides a detailed, animated walkthrough of how SQL Server performs index seeks using B-tree structures. It explains the role of root pages, intermediate directory pages, and leaf pages in navigating a clustered index to find a specific row (Id 12345). The author breaks down page labeling (e.g., 1:100), how SQL Server traverses the tree from root to leaf, and the limitations of 8KB pages. Aimed at database professionals and developers, it offers visual insights into index internals without overwhelming technical jargon.
