中国人民大学理工处V6 （ 中国人民大学 ）
技术摘要
描述了一种面向并发联机分析处理（OLAP）的数据库查询处理方法，在基于谓词向量的内存OLAP星形连接优化的基础上，实现了基于批查询谓词向量位操作的并发OLAP查询处理。针对数据库管理系统的I/O性能和并行OLAP处理性能，实现了并行查询处理优化技术，支持根据I/O性能优化设置并行OLAP处理负载，从而提高面向多种OLAP查询的可预测处理性能，实现基于谓词向量数组的并发查询星型连接位图过滤处理。
技术说明
A concurrent on-line analytical processing (OLAP)-oriented database query processing method is described, for performing, on the basis of predicate vector-based memory OLAP star-join optimization, concurrent OLAP query processing based on a batch query predicate vector bit operation. The concurrent query processing optimization technology is implemented for I/O performance and parallel OLAP processing performance in a database management system, and setting of concurrent OLAP processing load in an optimized way catering to the I/O performance is supported, thereby improving predictable processing performance oriented to diversified OLAP queries and implementing concurrent query star-join bitmap filtering processing based on predicate vector arrays.
