The invention provides a historical library synchronization method and system based on a power grid platform. The method comprises the following steps: a synchronous sending server receives sql data sent by a data change source through a message bus, and forwards the data to a write archive log thread and a TCP sending thread; the archive log writing thread stores the data into an archive log, and the TCP sending thread sends the data to a synchronous receiving server through a TCP link; the synchronous receiving server receives the data, forwards the data to a standby database writing and archiving log thread and a database interface, executes a storage operation and stores the data into an archiving log; when the synchronous receiving server side recovers from the fault state, a data state recovery message is sent to the synchronous sending server side, the synchronous sending server side retrieves unsynchronized data from the archived log and sends the unsynchronized data to the synchronous receiving server side through the TCP link, and the synchronous receiving server side stores the archived log and executes storage operation. According to the invention, the real-time performance, the reliability and the safety of the data are ensured.

The invention discloses a data management platform, a data management method, a data management device, a medium and equipment. The data management platform can store an intermediate execution result processed by each data processing layer into a second storage module in a process of executing a target code through a first data link of an execution module, so that when a backtracking operation needs to be executed for the target code, the backtracking operation can be executed for the target code. According to the data management platform, the intermediate execution result processed by each data processing layer of the first data link is obtained from the second storage module through the independent data link to perform the backtracking operation, so that the influence of the execution of the backtracking operation on the execution of the real-time data processing operation can be avoided, and the data backtracking capability of the data management platform is improved.
