Abstract: The present disclosure provides a generic multi-source heterogeneous large-scale data system, including a sync node config unit, an install & deployment unit, a block & pipelining unit, a unilateral sync unit, a bilateral sync unit and a correctness guarantee unit. The system operates on a middle layer which is above a node database layer and beneath an application logic layer. In a data synchronization process, a client end transmits captured local change information to a server end in accordance with a synchronization task plan; the server end receives and transfers the change information to an asynchronous parallel message processing mechanism to be stored in a corresponding message queue; the server end polls a local message queue for reading to-be-processed change information, and then performs subsequent data change in accordance with rules for heterogeneous data mapping, so as to maintain consistence of synchronized data objects between a source end and a target end.

Abstract: The present invention discloses a processing method of address-associated data, a user terminal and two servers, the method includes: transmitting a request for an electronic map to a map server (the first server); receiving the electronic map returned by the map server; selecting a region on the electronic map; transmitting a request for calculation of address-associated data on the region to an applied server (the second server); receiving a calculation result of the address-associated data on the region returned by the second server; and displaying the calculation result of the address-associated data on the region with the electronic map. This design and its implementation have significantly improved service response rate of processing and map-presenting massive address-associated data, hereby offered better user experience.
