Embodiment 2
[0060] The system in Example 1 is used as the county-level real estate information management network system and the metropolitan center real estate information management network system. The database servers of several county-level network systems and the metropolitan center database servers are connected by VPN through the wide area network. The county-level network systems The database server of the database regularly reports the information increase, decrease and modification content to the database server of the underground center. The systems at all levels can also only save the information of the database at the same level. When necessary, the upper-level database can query the data of the lower-level database at any time, and read the required data from the lower-level database.
[0061] The transaction and query methods are the same as those in Embodiment 1.
Embodiment 3
[0063] With the system in embodiment 2 as the city-level real estate information management network system, with the system in embodiment 1 as the provincial or directly-controlled central network system, the central database server of several prefectural-level network systems and the provincial or directly-controlled central database server pass The wide area network is connected by VPN, and the database servers in the city centers of various places regularly report the information increase, decrease and modification to the database servers in the city centers of provinces or directly under the Central Government. The systems at all levels can also only save the information of the database at the same level. When necessary, the upper-level database can query the data of the lower-level database at any time, and read the required data from the lower-level database.
[0064] The transaction and query methods are the same as those in Embodiment 1.
