Disclosed is a concurrent-OLAP-oriented database query processing method. On the basis of the predicate vector-based memory OLAP star connection optimization, the concurrent OLAP query processing on the basis of batch query predicate vector bit computing is performed. According to the present invention, in a database management system, for the I/O performance and the parallel OLAP processing performance, a concurrent query processing optimization technology is implemented and I/O-performance-oriented optimization and setting of a concurrent OLAP processing load is supported, thereby improving predictable processing performance of diversified-OLAP-oriented queries and implementing the concurrent query star connection bitmap filtering processing on the basis of an array of predicate vectors.
