Example forComplexBusinessTransactionActivity and ActionContext2 discussion December 8, 2006 (MM Role issue)

["Dale Moberg" <dmoberg@us.axway.com>]

Here is a sequence diagram overview of the message organization among 5 roles, buyer, seller, catalog service, credit rating service, credit monitoring service.

The scenario is that a Purchase Order Request is sent by a buyer to a seller who first checks the price of items using a catalog service, then proceeds to do a credit check on the buyer using a credit rating service that makes use of a credit monitoring service. The PurchaseOrder Confirmation is only returned after all these intermediate actions complete.

 

 

 

I have attached a Business Collaboration excerpt to illustrate the above roles and sequences.

 

The main observations I have made about this case and the problem that Monica raised:

 

1 The ActionContext2 needs to be modified to not only reflect nesting that can arise from the CollaborationActivity levels of nesting of BTAs, but also the nesting that can arise from the CBTA.

2. There can be more than one BTA at a given CBTA level of nesting, so ActionContext2 needs that identification identified also.

 

With these changes, I think the proposal to tie the Role value to the Role that is bound to the Requesting- or RespondingBusinessActivity Roles still can be used.

 

Here is the complexBTA textual excerpt and visualization.
