The business process model links activities that represent the sequence in which activities are performed at runtime. Embedded within the model is an implied data flow between activities and the business process context.
The business process context is the means by which runtime data instance management is exposed within the design-time environment. Individual activities require input or generate output so a centralized data source must exist and be available to all activities. Because any number of activities can be defined to use similar data types as their input or output, a means for differentiating between multiple instances of a given data type is also required. Thus, the business process context is effectively a global container of named data type instances that are accessible by all activities within a business process definition.
Before packaging a business process for the runtime engine, all activities must have all inputs and outputs defined with valid context references.
