| titleOfInvention | A kind of data query method and device based on big data environment |
| abstract | The invention discloses a kind of data query methods based on big data environment, comprising: when receiving the inquiry request of client input, parses to the inquiry request, obtains the context relation of the inquiry request, and form statement sequence；Based on metadata information, the sentence distinguished in order is analyzed, obtains the node and node types where data source；Generate data manipulation sentence corresponding with each node；The operating result that each node is fed back is aggregated into buffer pool, processing is merged according to statement sequence, generates query result, and the query result is exported to the client.The present invention further simultaneously discloses a kind of data query device based on big data environment.Using technical solution of the present invention, the unified query interface of Hadoop big data environment and relational database can be provided, compensate for existing relational database data and Hadoop big data environmental data can not direct intercommunication technical bottleneck. |
