Space-Filling Curves for Efficient Multidimensional Data Storage and Querying

This article introduces space-filling curves such as Z‑ordering, Hilbert, and XZ‑Ordering, explaining their mapping algorithms and how they transform multidimensional spatial data into one‑dimensional indices for efficient storage and querying in key‑value databases, while discussing challenges and practical examples.
