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.
