The application discloses a
data query method and device,
electronic equipment and readable storage medium. The method comprises the following steps: after receiving at least one
semantic query statement, mapping information of a
metadata graph atlas ontology is acquired, wherein the mapping information comprises a mapping relationship between a graph attribute class in the
metadata graph atlas ontology for describing a
data structure of a target
data source and configuration file information of a storage file in the target
data source; according to the mapping relationship and a graph attribute class corresponding to the
semantic query statement, configuration file information corresponding to the
semantic query statement is queried; a target storage file corresponding to the configuration file information is extracted from the target
data source; the target storage file is converted into a target
data set based on the
metadata graph atlas ontology; and semantic calculation is performed on the target
data set to obtain a query result corresponding to the semantic
query statement. The application solves the technical problem that the number of data islands increases rapidly in the prior art, which leads to excessive management
workload of data and reduces
data management efficiency.
