Multi-data source data query method and device, storage medium, terminal

Abstract

The invention discloses a multi-data source-based data query method and apparatus, a storage medium and a terminal. The data query method comprises the steps of receiving a plurality of data query requests of a data demander; making a response to the data query requests in sequence, and when the response to each data query request is made, starting from a next data supplier after an ending point of a previous data query request, polling multiple data suppliers until a query is finished, wherein the ending point of the previous data query request is the data supplier when the query of the previous data query request is finished; receiving a query result obtained when the query of the previous data query request is finished; and sending the query result to the data demander. Through the technical scheme, a multi-data source supply data-based data query method can be provided, so that the data suppliers have opportunities to provide the data for the data demander, the coverage degree of the data demander can be increased, and the data demander obtains the required data as far as possible.

Description

technical field [0001] The invention relates to the field of data circulation, in particular to a multi-data source data query method and device, a storage medium, and a terminal. Background technique [0002] In data transactions, there are multiple data sources (that is, data suppliers) that provide homogeneous data information. In order to obtain the required data information, the data demander often needs data support from multiple data sources. [0003] However, at the current stage, both parties to data transactions only have technical solutions for single-point data transactions. Even if there is data supply from multiple data sources, the single-point data transaction scheme cannot provide data from multiple data sources for the data demander, which will lead to the lack of equal opportunities for each data supplier to provide data for the data demander, and cannot satisfy multiple data requirements. The fairness requirements of the source supply data cannot meet th...

[0003] However, at the current stage, both parties to data transactions only have technical solutions for single-point data transactions

Even if there is data supply from multiple data sources, the single-point data transaction scheme cannot provide data from multiple data sources for the data demander, which will lead to the lack of equal opportunities for each data supplier to provide data for the data demander, and cannot satisfy multiple data requirements. The fairness requirements of the source supply data cannot meet the data coverage requirements of the data demander, and may even cause the data demander to fail to obtain the required data
