Abstract: A data indexing method is disclosed. In this method, N one-dimensional indexes that correspond to N dimensions and are independent of each other are obtained according to the N dimensions, and it is determined whether address records included in the N one-dimensional indexes have an intersection set, so as to obtain data pointed to by an address record corresponding to the intersection set, where the data is used as target indexing data, thereby solving the problem that a one-dimensional indexing technology cannot meet requirements for multi-dimensional indexing combined query and multi-dimensional analysis.
