Data processing method and device, electronic equipment and computer readable storage medium

The invention provides a data processing method and device, electronic equipment and a computer readable storage medium, and can be applied to the field of distributed databases. The method comprises the following steps: receiving a data access request, wherein the data access request comprises a to-be-queried customer parameter; determining a first parameter type corresponding to the to-be-queried client parameter and a second parameter type corresponding to a client parameter serving as a primary key in a second data table of the source distributed database; when the second parameter type is consistent with the first parameter type, accessing a source distributed database according to the to-be-queried client parameter; if not, accessing an aggregation distributed database according to the to-be-queried client parameters; wherein the aggregated distributed database comprises a first data table, the first data table takes a client parameter of the first parameter type as a primary key, and the aggregated dis
