General Board / BPMN Gateways

« on: March 08, 2009, 08:08:46 am »

I am using EA version 7.0. How does one show the different gateways (and, or , xor, complex), activity loops, event types, etc?  

I see the basic gateway and activity but I can find no way to show the specific types of gateways otr other specific language constructs.

Uml Process / XOR Disjunction applied to two associations

« on: June 24, 2009, 12:36:01 pm »

Hello,

Say I have a concept "Car" which is associated via the binary relation "ownedBy" with the concept "Person" and "Company". In other words ownedBy(Car,Person) and ownedBy(Car,Company). However I want the relation to be exclusive i.e.  

(ownedBy(Car,Person) or ownedBy(Car,Company)) and not(ownedBy(Car,Person) and ownedBy(Car,Company))

In the UML specification you draw a binary relation R₁ between Car and Person and R₂ between Car and Company. Then you draw a binary relation R₃ between R₁ and R₂ and finally you place and {xor} constrain on the relation R₃.

I cannot seem to be able to do this in EA. Is there a way to do this?

Regards,
Manny
