No-coupling backlog integration method and system

The invention discloses a no-coupling backlog integration method and system. A data capture server is utilized to simulate the request action of a user's browser to acquire required data, the data is sent to a target service system, the target service processes the obtained request data and returns the processed data to the data capture server in the format of a report, and the processes data is stored in a database of the data capture server. An original system needs no change to realize no-coupling system integration, and the situation that the original system cannot realize interface development is changed.
