Abstract
The present disclosure relates to a data query method and apparatus based on online analytical processing, a medium, and a device. The method includes: obtaining a plurality of target join keys between query tables in a structured query statement in response to reception of the structured query statement; constructing a first factor graph corresponding to the structured query statement based on the plurality of target join keys, where a factor node in the first factor graph is used to represent a conditional probability distribution in the case of presence of the target join keys in a query table corresponding to the factor node; and estimating an upper limit value of a join cardinality of the structured query statement based on the first factor graph.
