Abstract: Embodiments of the present invention relate to a call record synchronization method, a cloud platform, and a terminal. The method includes: detecting, by a first terminal, an input operation for requesting to display a call record; and after the first terminal detects the input operation, displaying, by the first terminal, a merged call record, where the merged call record is a call record obtained after merging of a call record of the first terminal and a call record of a second terminal, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal. According to the embodiments of the present invention, a user can use the merged call record to identify call answering or making statuses on a plurality of terminals, without querying a plurality of call records. This improves user experience.

Abstract: A batch data query method and apparatus are provided. According to the method, multiple logical query plan trees corresponding to multiple query statements are obtained. The multiple logical query plan trees are divided into multiple query groups according to operators of each logical query plan tree. Logical query plan trees in each query group have the following relationship: an inter-query write-read dependency relationship, an operator overlap relationship, or an operand overlap relationship. Then, inter-query optimization is performed on the logical query plan trees in each query group, and multiple corresponding physical query plan trees are generated according to the multiple optimized logical query plan trees. Finally, physical queries are executed according to the multiple physical query plan trees, to obtain query results of the multiple query statements.
