The invention discloses a response-based high-concurrency lightweight data integration architecture realization method and a system thereof. The data integration architecture comprises an integrated operation builder, an integrated operation trigger, an integrated operation scheduler, an integrated operation actuator, an integrated data extractor, an integrated data converter and an integrated data loader. The method comprises the following steps: building all kinds of data into integrated operation; starting the integrated operation according to the triggering mode of the integrated operation; specifying an integrated operation actuator for the integrated operation; generating an integrated data extractor, an integrated data converter and an integrated data loader for the integrated operation; extracting various types of integrated original data from an original external data source; converting various types of integrated original data to obtain integrated data serving as target data;and writing the target data into a target data source. The user of the invention directly introduces the data integration framework into the service application system, and then constructs the integration operation based on the data integration framework, thereby realizing concurrent expansion of the data integration close-up link.
