The invention discloses a data query method and device, a storage medium and a processor. The method comprises the steps of acquiring a query instruction, wherein the query instruction is used for querying first data in first type of data, and second data corresponding to the first data in at least one piece of second type of data; determining a first corresponding relation and at least one secondcorresponding relation according to the query instruction, and querying the first data in the first type of data, wherein the first corresponding relation is used for representing a corresponding relation between the data in the first type of data and a first identifier, the second corresponding relation is used for representing a corresponding relation between the data in the second type of dataand a second identifier, and the second identifier is determined according to the first identifier; querying a designated identifier corresponding to the first data according to the first corresponding relation in the first identifier; and querying the second data corresponding to the designated identifier in the at least one piece of the second type of data according to the designated identifierand the at least one second corresponding relation. According to the data query method and device, the technical problem of low efficiency of querying the data with an inclination characteristic is solved.
Description
technical field [0001] The present invention relates to the field of data processing, in particular to a data query method, device, storage medium and processor. Background technique [0002] With the continuous development of hardware and software technology, data warehouse has become the research key field of information management system based on database. Data query is the most frequent operation in information management system. In a relational database, data query is the process and technology of storing the selected and processed data into the relational data table, and based on this, generating query statements according to user needs, and querying the required data from the relational database. In essence, the role of data query is to extract business-oriented analysis-oriented data from relational data tables, and conduct summary analysis on business data. [0003] In the process of querying space intelligence data, due to the characteristics of high inclination ...
