Abstract: This article presents an algorithm that provides enhanced capabilities for representing keys in hierarchical structures. By using a binary representation of the materialized path, it allows efficient sorting of nodes through bitwise comparison and rapid computation of upper and lower bounds for all keys within the subtree. This methodology finds widespread application in database design and information filtering tasks. The study compares this algorithm with various approaches used in well-known database servers. The research findings confirm the effectiveness of the proposed method and its advantages over alternative approaches. It enables faster execution of sorting operations and computation of key bounds, which are critical for the efficient functioning of databases and processing large volumes of information. Therefore, the presented algorithm holds significant practical relevance and can serve as a valuable tool in the development and optimization of databases, as well as in other tasks related to information processing and filtering.

Keywords: trees data, hierarchies, relational database & models.
