The invention discloses a
data query method and related equipment. The method comprises the steps that firstly, after a
query language inputted by a user is obtained, a
query statement is analyzed toobtain first information and second information, wherein the first information is
data source information in which a query target is stored, the first information comprises third information and fourth information, the third information represents a
data type of a target
data set, the fourth information represents a storage identifier of the target
data set in a
data source, the target
data set isa data set required for performing query
processing on the query target, and the second information represents a feature identifier of the query target; secondly, a query action is determined according to the first information, and a target data set is determined from a data
pool according to the first information, wherein the data
pool comprises N data sources, each
data source comprises at least one data set, and the data types of the data sets stored in different data sources are different; and finally, a query target is determined by utilizing the query action and the target data set so as to improve the query efficiency.
