The invention discloses a closed-loop ecological feedback chain system based on a server and a webpage and relates to the field of webpage and server technology. According to the system, first, the webpage sends request data to an access layer, data query is performed through front logic and a multi-level cache, the server is called to perform source return processing, and data information is acquired; data isomerization and data atomization are performed, wherein data of all dependent systems is acquired, stored and atomized; through data atomization, a data closed-loop system can be better constructed; data aggregation is performed, wherein multiple pieces of atomic data are aggregated into one piece of module data for transmission in combination with a system architecture, and high-performance reading is provided for front-end page display; and for the data separated by a front-end display system, data coupling is reduced, and a closed-loop feedback chain between the server and thewebpage is completed. Through the system, a response can be quickly made to a user request when a large amount of access is received, so that user experience is improved; the problem that data acquisition is limited by a third-party interface is solved, redundancy brought by data dependence is avoided, and the ecological closed-loop chain is formed to lower maintenance cost.
