Abstract

The embodiment of the invention provides a data query method and device, and relates to the technical field of data processing, and the method comprises the steps: obtaining tax payer information; querying a relational graph containing the obtained tax payer information in a graph database to obtain a first relational graph, the graph database being used for storing the relational graph between each tax payer and the billing item; obtaining billing item information contained in the first relation graph; and querying a relational graph containing the obtained billing item information in the graph database to serve as a query result. When the scheme provided by the embodiment of the invention is applied to data query, richer query results can be obtained.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data query method and device. Background technique [0002] With the use of the tax information system, the staff can quickly query the tax information of taxpayers through the tax information system. In the prior art, after the staff enters the taxpayer's query target in the query window of the tax information system, the above-mentioned system queries the invoice data stored in the relational database according to the above query target, and obtains the query result.
