Abstract
Disclosed in the present application are a method of creating a materialized column based on a data lake and a method of querying data based on a data lake. In these methods, at least one materialized column can be created for a data table first, such that these materialized columns are used for storing data related to common columns in the data table, such that when a user subsequently triggers a data query request for a common column, a materialized column can replace the common column in feeding back the queried data to the user, and in this way, adverse effects caused when the queried data is fed back to the user directly by the common column can be effectively overcome, such that the data query effect can be effectively improved, and the information processing effect for such data tables can thus be effectively improved.
