Data calling method and device based on multiple data sources, medium and electronic equipment

The invention provides a data calling method and device based on multiple data sources, a medium and electronic equipment, and relates to the field of data processing.The method comprises the steps that a calling time set T is obtained in response to a received starting signal of a target polling event; obtaining a target time interval set G according to the T; according to G, obtaining a to-be-called target data source set S corresponding to the current target polling event; if S is not null, calling a target attribute value corresponding to the target subject from the corresponding target data source to obtain a target attribute value list set X; if the target attribute value corresponding to the MIN (Xj) is smaller than the current minimum target attribute value corresponding to the Sj, Ti is replaced with Tnow. According to the method for updating the calling time of the data sources, reasonable allocation of configuration resources of the target data sources is achieved, the more reasonable calling frequ
