Question
Make Activity Diagram draw from ATM Transaction with Object Node:
on Action: pin & Data Storage?
Draw answer based on object oriented modeling.
Below is draw example!
![OF - Object Node
. Notation variant: object node as parameter
• For Activities:
Input
parameter
• For Actions ("pins")
Action A
Assignment flow
ObjectName:type
[state]
ObjectName:type
[state]
ObjectName:type
[state]
ObjectName:type
[state]
Output
parameter
Action B
OF - Object Node: Data Store (DS)
DS is also special Object Node for
saving and passing on object tokens
.
.
.
Permanent memory
.
.
Saves object tokens permanently,
passes copies to other nodes
We can define queries regarding the
content of the DS at the outgoing
edges leading from the DS.
These queries are attached to the
outgoing edge using the note symbol.
A DS can therefore model the
functionality of a database.
