Abstract
With the rapid development of information technology, relational databases face challenges in storage and query efficiency when handling massive volumes of geographic elements. This study focuses on partition optimization for massive element storage in relational databases, aiming to enhance data management efficiency through rational partition strategies. Based on spatial feature and access pattern analysis, a novel method integrating multi-dimensional indexing with an adaptive partitioning algorithm is proposed. This method dynamically adjusts partition granularity according to the characteristics of data distribution, effectively reducing the number of I/O operations. Experimental results demonstrate that, across datasets of varying scales, the new method reduces average query response time by 35% and improves storage space utilization by 20% compared to traditional partitioning schemes. Additionally, an intelligent caching mechanism is introduced to further enhance overall system performance. This research not only provides effective technical means for massive element storage but also offers valuable references for big data management in other domains. Its innovation lies in the organic combination of spatial features and access patterns, achieving intelligent and dynamic partition strategies, which significantly improve the capability of relational databases in handling massive elements.
