So I am creating a Ordering System and having troubles on understanding how to implement my use case which are:

1.) CreateOrder

2.) UpdateOder

3.) ViewOrder

4.) DeleteOrder

Into a sequence diagram.

My actor are Primary Actor is Stock Clerk and Secondary Actor is Manager

• Create the Sequence and Collaboration diagrams for each use case identified
  • All objects should be identified in the diagrams, including other system objects.
  • Identify all methods needed to complete a use case.
  • Number all of the steps in a sequence to show the order in which the methods are called.
  • Convert the sequence diagram to a collaboration diagram.
  • Add all links and notations to the collaboration diagram.
