The invention discloses a command and control system database data synchronization system which comprises software modules such as a data synchronization service module, a data issuing subscription module, a data communication module and a data synchronization management module, and a database, wherein the data synchronization service module is used for executing data synchronization operation andsupports synchronous and asynchronous data synchronization; the data issuing subscription module is used for capturing updating situations of the database and used for packaging updating informationinto a message; the data communication module is used for achieving functions such as compression, encryption, encoding, transmission, decryption and assembling of the message, and then transmission requirements of low-network quality can be met; the data synchronization management module is used for achieving synchronization rule making, data requirement subscription and synchronous log checking.By adopting the system, defects that a conventional synchronization technique is rough in synchronization granularity, high in network environment requirement, and the like, can be solved.
Description
technical field [0001] The invention belongs to the field of information technology processing, and in particular relates to a database data synchronization system of a command and control system. Background technique [0002] Data is the basis for the stable operation of a multi-level command and control system. With the continuous expansion of the scale of the command and control system, the lower-level systems need to obtain corresponding data from the upper-level system in real time, and the problem of data synchronization between systems has also become prominent. The change of data can be sensed by other systems at all levels in time and data synchronization should be performed according to the corresponding needs, which has become a key technical problem that must be solved for the data service of the command and control system. Since the 1990s, scholars have conducted a lot of research on data synchronization technology between multi-level systems, and summarized sev...
