Abstract
Embodiments relate to cube construction. According to a method, a plurality of valid history queries that request to retrieve a cube comprising a first number of cuboids in an On-Line Analytical Processing (OLAP) system are collected. A plurality of dimension combinations is acquired from the plurality of valid history queries. A query frequency of each cuboid of a second number of cuboids with the plurality of dimension combinations is determined, the second number of cuboids being a subset of the first number of cuboids. A cuboid construction sequence for the second number of cuboids is determined based on the query frequency. The cube is constructed based on the cuboid construction sequence.
