Using Data Stores
Objects that are shared, supplied or used in processing can be stored in a data store.
A data store provides a mechanism to update or consult data that will persist beyond the scope of the current process. It enables storage of input message flows, and their retransmission via one or several output message flows.
Prerequisites to using data stores
HOPEX Business Process Analysis provides several types of data store:
• Process data store, associated to a concept domain.
A concept domain is a sub-set of elements of a business dictionary that reduces the scope of a field. For more details, see the
Hopex Data Architecture guide.
• Process logical data store, associated to a logical data domain.
A A logical data domain is used to define a logical data structure made up of classes and data views. For more information, see
Hopex Data Architecture.
To activate data stores options:
1. In the workspace, open the Options navigation window.
2. In the tree on the left, select HOPEX Solutions > Business Process Analysis.
3. Select the check boxes that interest you in the following fields:
• Activate former BPMN data stores (HOPEX V3 and lower)
If you cannot see the
Data Store button in your diagram, click the diagram
