The invention provides a cross-domain information system-oriented real-time on-demand data aggregation system and method. The system comprises a convergence end deployed in a target information systemand a plurality of source ends deployed in a plurality of source information systems, a convergence end connector and a source end connector establish virtual local area network tunnel mutual communication to form an overlay network; an aggregator collects aggregation requirements of various applications in a target information system for source data to form an aggregation rule, and gathers the data meeting the aggregation rule in the source information system; and a filter performs filtering operation on the data in the source information system according to the aggregation rule of the aggregator and transmits the data meeting application requirements to the aggregator in the target information system, and the aggregator provides an interface for an upper-layer application to acquire thedata. The invention provides a real-time cross-domain data aggregation framework which can dynamically customize data aggregation requirements, is millisecond-level in data transmission delay and iseasy to expand and update.
