Business patterns are templates of business objects and processes.
In modelling parlance they can uses parameters, partitions or delegation, but, contrary to representation patterns, abstraction is to be understood in terms of subsetting if the consistency and continuity of identities is to be maintained. Hence, the challenge is to provide a rigourous and non ambiguous description of core objects and activities, without second-guessing the design of system components. According to architecture driven modelling objectives, such a core should be limited to persistency and execution units and the associated dependencies.
