The Sequence Diagram is created from the Use Case Diagram and Class Diagram scenarios. The following figure represents a Sequence Diagram corresponding to the main scenario of the "Register Company" use case.

About the Sequence Diagram above, judge the following items:

I.The internal actor is the "Company", which is responsible for informing the data to perform the business registration.

II.As initial interface, the class "Register Company" is used. To register the companies, it is understood that the objects "Branch of Activity" and "Zip Code" are already registered.

For each object represented, it can be seen that a "lifeline" has begun, and when the object begins to interact, the focus of control is used, which has its messages in a numbered and orderly manner.

IV.After the execution of the operations, the receiving object "Company" sends a return message to the sender interface "Form_Cadastrar Empresa", represented in the dashed line.

Are the correct items?

What I have tried:

II.As initial interface, the class "Register Company" is used. To register the companies, it is understood that the objects "Branch of Activity" and "Zip Code" are already registered.

IV.After the execution of the operations, the receiving object "Company" sends a return message to the sender interface "Form_Cadastrar Empresa", represented in the dashed line.

Not too handy for showing "cycles". Every UML pattern seem to have at least one "yeah, but ...".

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

And your tutor is expecting your thoughts - not ours!

You show no attempt to solve the requirement by yourself, you have no question, your main effort is pasting the requirement, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.
Indeed, we can trow you a full blow up answer, but it will be magic to you and will defeat the purpose of homework.
So go on, even a wrong answer will be useful to help your tutor to spot your weaknesses.
