浅析利用Oracle物化视图对查询优化

Analysis of query optimization using Oracle materialized view

随着大数据、物联网、云计算等概念的兴起,关于数据的分析应用逐步从后台走向了前台,生活中各类的软件开发、终端应用都离不开背后支撑整个环境的数据本身,动辄上亿、甚至百千亿级别的数据亦不罕见,面对如此庞大的数据量,效率"二字"也被提升到了一个空前的高度上。Oracle作为目前使用最为广泛应用的关系数据库,如何对其做性能优化,提升工作效率,去促成更强的决策能力、洞察力与最优化处理,成为信息产业所有人聚焦的核心。本文从Oracle物化视图入手,结合日常工作,指出了基于Oracle物化视图性能优化方式。

With the rise of big data,Internet of Things,cloud computing and other concepts,the analysis and application of data has gradually moved from the background to the foreground.All kinds of software development and terminal applications in life are inseparable from the data behind the whole environment.In the face of such a huge amount of data,the efficiency has also been raised to an unprecedented height.As the most widely used relational database,Oracle is the core of the information industry's focus on how to optimize its performance,improve work efficiency,and promote stronger decision-making ability,insight and optimization.This article starts with Oracle materialized view,combined with daily work,points out the optimization method based on Oracle materialized view performance.
