The invention discloses a large data inquiring method based on distribution relation-object mapping
processing. The method includes the following steps that firstly, m
data processing nodes are selected, a Hibernate Session object is constructed for each
data processing node, a distributed Hibernate framework is obtained and a Session resource
queue is generated; secondly, a configuration file is set, a storage strategy and a routing strategy corresponding to a
list of each type are set, an S
list with a data volume is backed up at each
data processing node, and an L
list with a large data volume is stored to the m data
processing nodes in a blocking mode; thirdly, an input inquiring request is analyzed and a corresponding processor is selected according to the type of the inquiring request; fourthly, the selected processor selects the corresponding node from the resource
queue to process the inquiring request according to the inquiring request, the corresponding routing strategy, and a
processing result is protocoled. The large data inquiring method based on distribution relation-object mapping processing can obviously improve the rate of inquiring large data lists.
