Problems solved by technology

After the data management system completes the data synchronization operation, the FAM1 operating data in the BAM is consistent with the backup data in the BAM, and the consistency flag F=1 in the FAM1 is set, and the first data modification operation performed thereafter will make the FAM1 operating data in the BAM consistent with the Inconsistent backup data, and the timing of periodic data verification in the prior art cannot guarantee that the data verification operation will be performed immediately after the first data modification operation is completed, that is to say, it cannot be guaranteed that F in FAM1 will be set to 0 immediately after the first data modification, then In the time period T from the end of the first data modification operation to the end of the first data verification operation, even if the data synchronization opportunity arrives, the data synchronization operation may still be impossible due to F=1, resulting in FAM1 running data in BAM Inconsistent state due to loss of synchronization opportunity with backup data in BAM
During the time period T, if FAM1 is restarted, FAM1 will use the backup data inconsistent with the FAM1 operating data in BAM as the initial operating data, resulting in abnormal user operations

Embodiment 1

[0066] Embodiment one: in the present embodiment, after the data modification unit of BAM carries out the data modification operation for the first time, notify the data verification unit of BAM to carry out data verification immediately, by the data verification unit among the FAM1 revise consistency sign F in real time according to verification result, make The consistency flag F can identify the fact that the FAM1 operating data in the current BAM is inconsistent with the backup data in the BAM.

[0067] Figure 5 is a structural diagram of the distributed data management system in Embodiment 1 of the present invention, Figure 5 Take BAM and a certain FAM among the multiple FAMs, such as FAM1, as an example. The distributed data management system in this embodiment includes: FAM1 101 and BAM 102 .

[0068] Among them, FAM1 101 includes: application module 110, data management module 113, communication module 114, memory data area 115 and backup data area 116, data manage...

Embodiment 2

[0079] Embodiment two: in this embodiment, after the data modification unit of BAM carries out the first data modification operation, immediately notify the data modification unit in FAM1 to modify the consistency mark F in real time, so that the consistency mark F can identify the FAM1 operating data in the current BAM and Inconsistent backup data in BAM.

[0080] Figure 8 is a structural diagram of the distributed data management system in Embodiment 2 of the present invention, Figure 8 Take BAM and a certain FAM among the multiple FAMs, such as FAM1, as an example. The distributed data management system in this embodiment includes: FAM1 101 and BAM 102 .

[0081] Among them, FAM1 101 includes: application module 110, data management module 113, communication module 114, memory data area 115 and backup data area 116, data management module 113 includes: data modification unit 177, data synchronization unit 179 and consistency flag F 170 . The BAM 102 includes: a human-...

Abstract

The present invention discloses a data management system, which contains setting consistency sign in BAM, after data management system completing data synchronization operation, FAM in BAM operating data and reaching concordance with BAM backed data, configuring consistency sign, when occurs first data modification after that, immediately configuring consistency sign as discordance. The present invention provides a data management method. The present invention provided data management system and method can in time label the discordance status between the FAM operating data and FAM backing up data in BAM.

Description

technical field [0001] The invention relates to data management technology, in particular to a distributed data management system and a data checking and data synchronization method of the distributed data management system. Background technique [0002] The distributed data management system commonly used in current communication devices includes multiple front management systems (FAM) for executing application tasks and a user-oriented back management system (BAM). BAM centrally stores and manages the operating data of multiple FAMs. Each FAM only stores and manages its own operating data and the backup data of the operating data. When the FAM restarts, the backup data is used as its initial operating data. When BAM receives a data modification instruction from a user for a certain FAM such as FAM1, BAM modifies the FAM1 operating data stored by itself in real time according to the data modification instruction, and notifies FAM1 to modify its operating data in real time t...
