The invention relates to a data processing method and device, an electronic device and a storage medium, and relates to the technical field of big data, and the method comprises the steps: obtaining metadata in a data obtaining request; matching each metadata in the data acquisition request with the metadata of each preset data table to obtain a candidate data table matched with the data acquisition request; wherein at least one metadata of the candidate data table is matched with at least one metadata in the data acquisition request; screening the candidate data tables with the same matched metadata to determine a predetermined number of target data tables, and obtaining values of the matched metadata from the target data tables; and determining the value of the metadata in the data acquisition request according to the value of the matched metadata in the target data table. According to the invention, the value of the metadata corresponding to the data acquisition request can be rapidly and accurately acquired, and rapid and intelligent access is realized.
