Understanding Data Concepts
A process instance has access to local (private) data, global data, and external data during process execution. After a process terminates the process data is eliminated.
Such data is provided in specific data models:
-
local data: business object model
-
global data: definition object model, entity relation ship model
-
external data: service object model
Parent and child models are using input/output data mapping to exchange data between models.
