The invention discloses a user state statistics system and a user state statistics method, which at least can solve technical problems that the conventional stand-alone statistics mode is limited by the processing speed and the memory capacity of a single server and consequently cannot satisfy the demand of massive growth of Internet users, cannot support expansion and has poor backup effect for disaster recovery. The user state statistics system comprises a server cluster, and a SSDB database connected with the server cluster, wherein the server cluster comprises a plurality of server nodes, each server node is respectively used for processing a dotting request sent by each user terminal, generating a user state message according to the dotting request and providing the user state message for the SSDB database; and the SSDB database is used for performing statistics on the user state message provided by each server node, generating user state information according to the statistics result and storing the user state information.

A disaster recovery switching method, a node and a system are provided. The method is applied to a disaster recovery switching system. The disaster recovery switching system includes a production node, a disaster recovery node and a recording node. The production node currently runs a first production service. The method includes the steps that the recording node receives first recovery information sent by the production node, wherein the first recovery information refers to the information required for recovering the first production service to a latest running state of the first production service; and the recording node sends second recovery information to the disaster recovery node when it is determined that the first production service is recovered on the disaster recovery node, wherein the second recovery information refers to the information required for recovering the first production service on the disaster recovery node obtained according to the first recovery information tomake the disaster recovery node switch the first production service to the disaster recovery node according to the second recovery information. The disaster recovery switching method, the node and thesystem can achieve the seamlessly switching of business, ensure the normal operation of the business, improve the stability of the production service and effectively avoid data loss in the event of asudden disaster on the production node.

The invention discloses a data management method and device of a single-chip microcomputer, a computer readable storage medium and a system. The data management apparatus includes an address acquisition unit and a data management unit. According to the data management method and device, the computer readable storage medium and the system, the read first data is verified, and output or correction is carried out according to the verification result and the backup sector data, so that the data security and the data stability of a single-chip microcomputer system are enhanced; furthermore, according to the data management method and device of the single-chip microcomputer, the computer readable storage medium and the system provided by the invention, a data rollback function is added, so that the disaster recovery capability of the data is enhanced, and the data stability is further improved.
