Zusammenfassung:	The invention relates to the technical field of data collection, and discloses a transaction data supplementary collection method and device, and the method comprises the steps: determining a data source where transaction data to be subjected to supplementary collection is located according to a supplementary collection operation instruction; acquiring a database type and configuration information corresponding to the data source, and establishing a plurality of data transmission channels (which can be parallel) with the data source; according to the supplementary collection starting and ending time and a preset supplementary collection period, calculating preset supplementary collection times and a current data time range; and based on the data transmission channel, the preset supplementary collection times and the current data time range, extracting the transaction data to be supplementary collected from the data source. Compared with a supplementary collection mode that all transaction data tables are coll
