Answer 6

Sequence Diagrams and Communication Diagrams

Question 7

Sequence Diagram is divided into what?

Answer 7

Sequence Diagram is divided into lifelines

Question 8

What is Focus of Control?

Answer 8

Shows a period of time in which an object is performing an action

Question 9

How do objects collaborate within diagram?

Answer 9

Collaborate through messages

Question 10

Types of messages in Sequence Diagrams?

Answer 10

Regular Messages

Special Messages

Question 11

What are Regular Messages?

Answer 11

Regular messages represent a directional communication from a client to a supplier

Question 12

What are Special Messages?

Answer 12

Create and Destroy messages represents the creation or destruction of an object
Return Messages specify return information being provided back to the client

Question 13

What are interaction operands?

Answer 13

They represent a region in the combined fragment

Question 14

What are Interaction Constraints?

Answer 14

Represent a guard that determine the control path taken

Question 15

Types of Combined Fragments?

Answer 15

OPT
ALT
LOOP
PAR
CRITICAL

Question 16

What is OPT?

Answer 16

Optional fragment that executes if the specified guard is true

Question 17

What is ALT?

Answer 17

Alternative that defines mutually exclusive options conditional logic expressed through guards

Question 18

What is LOOP?

Answer 18

Fragment that repeats while the guard is true or for a given number of times specified

Question 19

What is PAR?

Answer 19

Fragments that can execute in parallel

Question 20

What is Critical?

Answer 20

Defines a critical region that cannot be interleaved with other messages from parallel fragments for example

Question 21

What is Interaction Use?

Answer 21

Interaction use defines a reference to an existing sequence diagram

Question 22

What are Gates?

Answer 22

Gates are used to allow the communication of messages between sequence diagrams
