All,
Working on SCEA part II. Developing component diagrams. I have few questions:
1. Login is a pre-requisite. Do I need to show this in my component diagram?. If yes, please clarify how can I do?
2. Also, the Usecase has a pre-condition and post-condition. How do I show these conditions in my component diagram?

Please reply asap, as I am hurrying

Thanks in advance.

Hi,

Component diagrams are structural diagrams, they do not show behaviour.
IMHO being authenticated in is a step within the behaviour of the system.

Cheers,
Marcel

A component diagram shows components (as is indicated by the name). It does not show state, conditions, or behaviour.

This is important to understand.

So,

1. You could include a login-component. It depends on what you want to show.
2. You do not show pre- or post-conditions in your component diagram.
