Method and system for synchronizing network administration data in network optimizing system

This invention discloses the method and the system of data synchronization in the Network Management in Optimization of Network System. This method includes the setting and saving Module of the Metadata, the data collecting Module, and the data filtering and saving Module. The first module is used to set and save the Metadata, which is saved in the form of the configuration and is independent from the original data system. The second module is used for the construction of the communication connection in data collection, the execution of the data collection after the organization of the searching requirement, and the saving of searching data in the temporary storage area. The third module is used for the data saving after the cleaning and the filtering of the data in the temporary storage area. Because of the Metadata independence from the original data system, the database of the network management and optimization is supported at the same time. The collection and the recollection is set to ensure the data integrity, especially in the rage of the different data.
