Data real-time synchronization processing method for library management system facing dynamic updating of library stock

Abstract

The application provides a book management system data real-time synchronization processing method for dynamic updating of a book inventory, relates to the technical field of book management, and comprises the following steps: real-time monitoring of book inventory data change events of each book management terminal and a background server end, if a change is monitored, a change trigger signal carrying a change end identifier and a timestamp is generated; based on the change trigger signal, incremental change data is captured to analyze a book identifier, change content and an operation type, and a plurality of key frame identifier nodes corresponding to a transmission protocol encapsulation layer of the incremental data are extracted as dynamic anchor points to form an anchor point coordinate set; the anchor point coordinate set is bound with the incremental data packet and is synchronized to all other terminals and servers, so that each receiver simultaneously obtains the incremental data to be processed and the corresponding anchor point coordinate set. The application can realize real-time and strongly consistent synchronization of book inventory data between multiple terminals and a background server, and avoids inventory data errors caused by concurrent operations.
