Abstract: A method for scheduling a multi-node cluster of K-DB database, comprising: connecting an application terminal and scheduler to a cluster of K-DB database through a service extranet, and connecting respective nodes in the cluster through an intranet; in response to that an application request is received by the scheduler, determining whether the request is a table query, and in response to that the request is the table query, determining whether the request is a multi-table-joint query; in response to that the request is the multi-table-joint query, determining tables to be queried, and determining nodes having a highest table version; determining types of change values of the respective tables, and calculating amount of updated data of the respective tables; and selecting a node with the smallest amount of updated data as a computing node, synchronizing the tables of other nodes to the computing node, and executing the multi-table-joint query.

Abstract: A data security realization method and system based on a K-DB database are provided. The method includes: receiving a data processing request of a user regarding a data table in a database; in a case where the data processing request is a data insertion action request regarding the data table, successively executing hash and encryption actions on inserted data, and storing encrypted data in an encrypted permanent hash table; and in a case where the data processing request is a data modification action regarding the data table or a data deletion action regarding the data table, generating an instruction for prohibiting data modification or data deletion. By virtue of the solution, the flow of prohibiting data modification and data deletion regarding a data table is optimized, and a hash value is encrypted, so that the function is more secure and strong.
