1. A computer implemented method for processing after image data, the method comprising: receiving a first after image business graph, wherein the first after image business graph comprises a result of a query against a data source after the data source has changed, wherein the first after image business graph does not show changes in the data source, wherein the first after image business graph contains data objects in a service data objects (SDO) framework, and wherein the after image business graph is received from a first enterprise information system comprising a an order taking and modification system; performing a first transformation on the first after image business graph to produce a generic after image business graph; performing a second transformation on the generic after image business graph to form a second after image business graph; receiving information defining a delta, wherein the delta represents changes to the first after image business image, wherein information defining the delta is received from a second enterprise information system, and wherein the first enterprise information system and the second enterprise information system comprise different system formats; performing a third transformation of the second after image business graph to form a delta business graph using the delta; and performing a fourth transformation of the delta business graph to form a generic delta business graph, wherein the generic delta business graph shows changes in the data source, and wherein the generic delta business graph contains data objects in a service data objects (SDO) framework.
