Abstract

The invention provides a CS architecture-based multi-terminal non-inductive real-time data pushing method, which is different from the traditional data stream pushing mode, separates data analysis and data pushing into two independent processing tasks, and stores data information by creating a local buffer zone, so that the two tasks are linked together, when a server receives data to be updated, the data is not independently and immediately sent to a client, but is stored in a structure body of a local buffer memory, and update information of additional data field record data is updated. The server periodically transmits the data to be updated in all the local cache structures to all the registered clients, and the operation is transparent to the data analysis process, so that the data update of the noninductive multi-terminal can be realized.
