The data allocating system, which is applied on a relational data node and distributed data nodes, includes a memory and a processor. The processor accesses a set of instructions from the memory and executes the set of instructions. The processor includes a correlation analyzing module, a query analyzing module, a performance analyzing module, and a decision module. The correlation analyzing module generates a correlation result according to a correlation of tables stored in the relational data node. The query analyzing module generates a query result according to queries in the log reports of the relational data node. The performance analyzing module generates a performance result according to execution times of the query result being executed by each of the distributed data nodes. The decision module selects the tables to be transferred to the distributed data nodes according to the correlation result, the query result and the performance result.
A data allocating system, applied on a relational data node and a plurality of distributed data nodes, the data allocating system comprising:
A data allocating method, applied on a relational data node and a plurality of distributed data nodes, the data allocating method is executed by a processor, and the processor comprises a correlation analyzing module, a query analyzing module, a performance analyzing module, and a decision module, the data allocating method comprises:
