Abstract

An adaptive materialization method for a database, wherein the method is executed by an electronic device. The method includes: determining a data connection execution plan for a database, wherein the data connection execution plan is used for performing data connection on a driving table and a driven table in the database, the data connection execution plan comprises execution sub-plans sequentially executed for each data record in the driving table, and the execution sub-plan executed each time corresponds to one data record in the driving table (101); selecting one data record from the driving table, executing, for the selected data record and on the driven table, an execution sub-plan for the data connection, and detecting execution information during the execution of the executing sub-plan (102); on the basis of the execution information, performing a materialization operation on the driven table, so as to obtain a materialized table (103); and performing data connection on the driving table and the materialized table, so as to replace the data connection execution plan (104).
