大数据环境下的数据仓库设计与优化
摘 要
随着大数据技术的迅猛发展,传统数据仓库面临性能瓶颈与扩展性不足的问题,亟需适应新时代的数据处理需求。本研究旨在探索大数据环境下的数据仓库设计与优化方法,以提升其在海量数据处理中的效率与灵活性。通过引入分布式架构、列式存储及多维索引等关键技术,并结合实际应用场景进行实验验证,提出了一种基于分层存储与动态负载均衡的优化方案。结果表明,该方案显著提升了查询响应速度和系统吞吐量,同时降低了资源消耗。本研究的主要创新点在于将机器学习算法融入数据仓库的自动调优过程,实现了对数据访问模式的智能预测与动态调整。这一贡献为大数据环境下的数据仓库设计提供了新的思路,也为相关领域的实践应用奠定了理论基础。

Abstract
With the rapid development of big data technologies, traditional data warehouses are encountering performance bottlenecks and scalability limitations, necessitating adaptations to meet the demands of modern data processing. This study focuses on exploring the design and optimization methods of data warehouses in a big data environment to enhance their efficiency and flexibility in handling massive datasets. By incorporating key technologies such as distributed architectures, columnar storage, and multi-dimensional indexing, and validating them through experiments based on real-world application scenarios, an optimized solution leveraging hierarchical storage and dynamic load balancing is proposed. The results demonstrate that this approach significantly improves query response times and system throughput while reducing resource consumption. A major innovation of this research lies in integrating machine learning algorithms into the automatic tuning process of data warehouses, enabling intelligent prediction and dynamic adjustment of data access patterns. This contribution not only provides new insights into the design of data warehouses in big data environments but also establishes a theoretical foundation for practical applications in related fields.
