Data table field attribute determination method and device, equipment and storage medium

The invention discloses a data table field attribute determination method and device, equipment and a storage medium. Aiming at each source data table, determining whether each target field attribute identifier in the current source data table and the attribute statistics frequency of the attribute identifier correspond to a downstream data table or not; for each target field, if a downstream data table corresponding to the current target field exists, superposing the attribute statistics times of each attribute identifier of the current target field to the attribute statistics times of the corresponding attribute identifier of the corresponding target field in the corresponding downstream data table; if the corresponding target field in the corresponding downstream data table further corresponds to the downstream data table, taking the target field as the current target field, and returning to the step of superposing the number of times of attribute statistics until the downstream table corresponding to the
