一种基于多连接属性划分的查询优化算法
A Query Optimization Algorithm Based on Multiple Join Attribute
摘要
Abstract
Database query operation is the most common operation. Because the data in a distributed database is distributed and redundant, query optimization study of a distributed database is one of the core issues. In order to improve the efficiency of distributed database queries, the paper analyzes and discusses the common implementation strategy based on the direct-join, and presents an improved direct-join query optimization strategy for the distributed database applications for multi-table joins when there are multiple connection properties. Improved algorithm improves query execution parallelism, reduces the query processing time and improves the query efficiency.关键词
