A data storage method includes obtaining at least one data record, each data record includes one carrier identifier and at least one label value, the at least one data record is stored in a data table, and the data table is used to record a correspondence between a carrier identifier and a label value; and creating a bitmap index corresponding to the at least one data record, where the bitmap index includes at least one bitmap; each bitmap corresponds to one label value; each bitmap includes at least one bitmap position, and each bitmap position is used to record whether a carrier corresponding to one carrier identifier has a label value corresponding to a current bitmap.

Data storage method and apparatus, and storage medium

An information processing method and apparatus, where the method includes: obtaining a user information table; creating, based on the user information table, a bitmap index including a plurality of bitmap vectors; creating a user identifier array based on the user information table; receiving a query request sent by a client; querying the user information table based on the bitmap index, the user identifier array, and at least one attribute value, to obtain a query result; and sending the query result to the client. In the foregoing manner, second-level indexing for an ad hoc query can be implemented.
