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.

Abstract: Embodiments of the disclosure provide methods, systems, computer program products for accessing web pages interactively are disclosed. According to the method, a web page comprising a plurality of user interface elements is accessed. Then information comprising identifications of the plurality of user interface elements and hot keys corresponding to the plurality of user interface elements is obtained. And then the information is sent to an assistive tool for being read out. In response to a hot key corresponding to a user interface element being input, an action corresponding to the user interface element is executed.
