The application discloses a data warehouse layer-by-layer carrying control method based on segmented construction, and relates to the technical field of data processing.The method comprises the following steps: calling a theme domain ETL log, taking a dependency priority as a constraint, and mining a hierarchical dependency topology; extracting an adjacent business domain to combine a segmented allocation function to construct an edge function node; configuring a data channel according to the hierarchical dependency to form a processing topology; and K layers receiving source data, progressively performing mutual verification and upward carrying, and outputting a result.The method solves the technical problems that the dependency relationship between business theme domains is complex and lacks hierarchical constraints in the existing data warehouse ETL processing process, leading to chaotic data processing links, easy propagation of errors, and difficulty in guaranteeing data consistency, and achieves the technical effects of automatically mining business dependency priorities through historical processing logs, constructing hierarchical dependency topologies and allocating edge function nodes, realizing mutual verification of intra-layer data and layer-by-layer carrying of inter-layer data in the processing process, and improving the accuracy, consistency and automation level of data processing.
