The invention relates to
database data sample acquisition, and belongs to the technical field of
database data query. During the data sample acquisition process, each data is subjected to the data screening and
processing process that whether each data satisfies a data sample acquisition rule or not is judged to obtain the rule satisfaction case of each data; whether the rule satisfaction case of each data exists in a target
list used for recording data samples or not is judged, if the rule satisfaction case of the data exists in the target
list, the data is not acquired to the target
list, if the rule satisfaction case of the data does not exist in the target list, the
data needs to be acquired and is updated and stored in the target list, and the rule satisfaction case corresponding to the data is also updated and stored in the target list. The existing data sample of the target list is displayed, based on the display, whether the corresponding data sample acquisition rule needs to be adjusted and configured or not can be operationally judged. By employing the
database data sample acquisition method, automatic and continuous acquisition can be achieved easily, the
data acquisition and query efficiency is high,
data redundancy is less, and the rule is flexible and changeable.
