1. A method for operating a ground milling machine having an interchangeable milling drum, wherein the milling drum is equipped with a plurality of milling tools, wherein the milling drum has a current state, wherein a control unit is provided for controlling at least one function of the ground milling machine, and wherein the milling drum is associated with a characteristic feature, the method comprising:
storing at least one data set containing information on the current state of the milling drum in a database, wherein the characteristic feature and the at least one data set are linked in the database, and wherein a computing unit separate from the milling drum comprises the database;
receiving, at the computing unit, a signal representing detection of the characteristic feature, wherein the data set linked thereto is retrieved from the database;
transmitting the data set to a processing device on the milling machine; and
determining and applying one or more machine parameters for operating the milling drum to perform a specified upcoming milling task based on the current state of the milling drum.
