The invention discloses an intelligent accurate
data quality management system, method and device, and relates to the technical field of
data quality management. When a rule is changed, a rule updating event is generated and published through Kafka, when the rule is updated, the difference between a new rule and an old rule is detected, and when the difference exceeds the expectation, a
rollback mechanism is automatically triggered, so that the accuracy of the
data quality management is improved. Verifying the preprocessed data by using a preset rule, classifying the abnormal data to obtain a plurality of abnormal data classes, and automatically correcting the classified abnormal data; identifying and classifying abnormal data which still cannot be corrected, migrating an isolated
data class obtained by identification to an isolated
queue from a main
data stream, retaining the abnormal data which cannot be processed immediately in the isolated
queue, and regularly reminding a data receiving end to process the abnormal data; and the exceptions which cannot be processed in real time are continuously left in the isolation
queue, and a data receiving end is notified at a constrained reminding frequency so as to ensure that the potential high-risk exceptions are not accumulated for a long time.
