Rasha Moh'd Altarawneh, Fatima Thaher Aburomman . A Fast and Scalable Approach for National Number Storage using Radix Tree Structure. International Journal of Computer Applications. 187, 81 ( Feb 2026), 32-34. DOI=10.5120/ijca2026926415
In this paper, modern administrative and security systems must be able to store and retrieve national identity numbers efficiently. Large-scale identity databases provide some methods such as linear or binary search trees, when connected to large-scale identity datasets the performance may be less than expected. This research proposes an intelligent and optimized lookup system for national ID numbers based on a Radix tree structure, which enables quick and memory-efficient retrieval of identity records. By representing each national number as a sequence of characters (digits), and organize them hierarchically in a Radix tree, the proposed model achieves near-constant time complexity for lookup and insertion operations.
