面向大数据的数据库存储优化策略
摘 要
随着信息技术的迅猛发展，大数据时代来临，数据量呈现爆炸式增长，这对数据库存储带来了巨大挑战。传统数据库存储在处理海量、高维、多源异构的大数据时存在诸多问题，如存储效率低下、存储成本高昂等。为解决上述问题，本研究旨在探索面向大数据的数据库存储优化策略。通过分析大数据的特点，结合分布式存储架构的优势，提出一种基于数据特征分类与分布式存储相结合的方法。该方法首先对数据进行特征提取与分类，依据不同类别数据的特性选择合适的存储方式，并利用分布式存储架构实现数据的高效存储。实验结果表明，相较于传统存储方式，此方法能够显著提高存储效率，降低存储成本，在数据读写速度方面也有明显提升。

Abstract
With the rapid development of information technology and the advent of the era of big data, the amount of data presents an explosive growth, which brings great challenges to database storage. Traditional database storage has many problems in dealing with massive, high-dimensional and multi-source and heterogeneous big data, such as low storage efficiency and high storage cost. To solve the above problems, this study aims to explore the database storage optimization strategies for big data. By analyzing the characteristics of big data and combining the advantages of distributed storage architecture, a method combining data feature classification and distributed storage is proposed. This method firstly extracts and classifies the data, selects appropriate storage methods according to the characteristics of different categories of data, and realizes efficient storage of data by using distributed storage architecture. The experimental results show that, compared with the traditional storage method, this method can significantly improve the storage efficiency, reduce the storage cost, and significantly improve the data reading and writing speed.
