1. A computer-implemented method comprising: receiving a request to perform a particular operation of a particular type on each of a plurality of model entities included in at least one digital meta model, each model entity modeling at least one attribute of a respective software component, wherein the request includes an identification of the particular type of operation, and the particular type is one of a plurality of operation types; retrieving the plurality of model entities from at least one memory device in response to the request; instantiating, using at least one processing device, a handler object of the particular type adapted to perform the particular operation by calling a set of reusable software modules from a plurality of reusable software modules stored in at least one memory device, each software module providing functionality used to perform at least a portion of the particular operation on at least one entity in the plurality of entities; and generating result data, using at least one processing device, based on the performance of the particular operation using the instantiated handler object and the set of reusable software modules.
