基于Oralce数据库SQL查询优化研究

过去的Oracle数据库优化算法要求相关技术人员必须具备非常专业的数据库理论知识,且在基于数据库的应用程序开发过程中缺乏较强的适用性,从而造成用户识别度较低,查询性能较差.为了处理好这一问题,本文分析了Oracle数据库SQL查询语句的基本处理过程,并提出了基于Oralce数据库SQL查询优化的几种技术方法,以期能够充分发挥出Oracle数据库的优势.

Based on Oralce database SQL query optimization research

in the past the Oracle database optimization algorithm requires related technical personnel must have very professional theory knowledge, database and application development process based on the database of the lack of strong applicability, resulting in the user identification degree is low, poor query performance. In order to deal with this problem, this paper analyzes the basic process of Oracle database SQL query, and puts forward the several techniques based on Oralce database SQL query optimization method, in order to give full play to the advantages of the Oracle database.
