39 a loop frame and an asterisk mean the same thing in a sequence diagram.

A sequence fragment is represented as a box that frames a section of interactions between objects (as shown in the examples below) in a sequence diagram. It is used to show complex interactions such as alternative flows and loops in a more structured way. On the top left corner of the fragment sits an operator. See Page 1. _____ is based on the idea that people classify things in terms of similarities and differences. cardinality. The number of links/associations that occur among objects in an entity relationship diagram is called ____. Association relationship.

A loop frame and an asterisk mean the same thing in a sequence diagram. True An activity diagram and the flow of activities in a fully developed use case description serve the same purpose.

A loop frame and an asterisk mean the same thing in a sequence diagram.

Sequence Diagram is an interaction diagram that details how operations are carried out -- what messages are sent and when. Sequence diagrams are organized according to time. The time progresses as you go down the page. The objects involved in the operation are listed from left to right according to when they take part in the message sequence. In general, frames consist of some region of a sequence diagram that is divided into one or more fragments. Each frame has an operator and each frag-ment may have a guard. (Table 4.1 lists common operators for interaction frames.) To show a loop, you use the loop operand with a single fragment and put the basis of the iteration in the guard. i don't think it's appropriate for a sequence diagram. the sequence diagram should describe a sequence (as the name hints). in my opinion it should be a sequence from a use case. if the use case has extensions (these represent control flow), then make one sequence diagram for each extension. let the programmer combine this with state diagrams, and then decide if an if-statement is the correct ...

A loop frame and an asterisk mean the same thing in a sequence diagram.. It does not try to identify the messages at the same level of detail as is done with a sequence diagram. CRC cards gives an overview of the process, but leaves many details to the programmer. Sequence diagram goes more in depth. 8. Explain the syntax of a message on a sequence diagram. '*' - means multiply occurring or looping A loop frame and an asterisk mean the same thing in a sequence diagram. True. In a system sequence diagram a box refers to a class of objects. False. ... On a sequence diagram when multiple messages are included within a repeating loop a(n) _____ is used to document it. loop frame. Sequence diagrams describe interactions among classes in terms of an exchange of messages over time. They're also called event diagrams. A sequence diagram is a good way to visualize and validate various runtime scenarios. These can help to predict how a system will behave and to discover responsibilities a class may need to have in the process ... System sequence diagram. d. System sequence diagram ... A loop frame and an asterisk mean the same thing in a sequence diagram. ... c. Asterisk * d. Opt frame e. Loop frame f. Alt frame. c. Asterisk * e. Loop frame. A textual model that describes the processing details of a use case is called aNo _____.

4. Avoid sequence diagrams if you are dealing with simple logic. One of the most common mistakes that most of us do is waste precious time doing too many sequence diagrams for every single use case, one for the basic course of action and one for each alternate course. It is best to design a sequence diagram only when you have complex logic that ... A sequence fragment is represented as a box, called a combined fragment, which encloses a portion of the interactions within a sequence diagram The fragment operator (in the top left cornet) indicates the type of fragment Fragment types: ref, assert, loop, break, alt, opt, neg Massimo Felici Sequence Diagrams c 2004{2011 (1 point) In a system sequence diagram the order of the messages is determined by numbering the messages. 7. (1 point) A true/false condition on a sequence diagram indicates whether the message can be processed or not. 8. (1 point) A loop frame and an asterisk mean the same thing in a sequence diagram. 9. False True A loop frame and an asterisk mean the same thing in a sequence diagram. 1 / 1 pts Question 93 The guard-condition on a transition indicates what? Correct! Whether the transition fires. Whether the object is in the correct state. Whether the action-expression executes. Whether the trigger message is received.

Sequence diagram describes a set of interactions sequences. opt fragment in diagram means that the diagram describes two possible interactions sequences - one with the interaction in the opt fragment and another without this interaction. The condition that describes may range from some deterministic calculation (2+2==4) to user choice (red pill selected) to random event (atom decays). That means the 22nd word is represented with this address. Dividing this address into two parts makes this easy. First four bits, that is block number(0101) gives number 5. that means it is 5th line. The number of associations that occur among specific things in an entity from COMPUTING ict2622 at University of South Africa Treat sequence diagrams as a visualization of how objects interact rather than as a way of modeling control logic. That said, here's the notation to use. Both loops and conditionals use interaction frames, which are ways of marking off a piece of a sequence diagram. Figure 4.4 shows a simple algorithm based on the following pseudocode:

False. ... in a system sequence diagram the order of the messages is determined by numbering the messages. false. True / False another name for the data model is the domain model.

UML Communication Diagrams Overview. Communication diagram (called collaboration diagram in UML 1.x) is a kind of UML interaction diagram which shows interactions between objects and/or parts (represented as lifelines) using sequenced messages in a free-form arrangement.. Communication diagram corresponds (i.e. could be converted to/from or replaced by) to a simple sequence diagram without ...

An important thing to note about breaks is that they only cause the exiting of an enclosing interaction's sequence and not necessarily the complete sequence depicted in the diagram. In cases where a break combination is part of an alternative or a loop, then only the alternative or loop is exited.

Question 2 A loop frame and an asterisk mean the same thing in a sequence diagram. Select one: True. False. Question 3 On a system sequence diagram, a message represents a service request. Select one: True. False. Question 4 On a system sequence diagram (SSD), an Opt frame and an Alt frame do essentially the same thing. Select one: True. False.

A loop frame and an asterisk mean the same thing in a sequence diagram. True. On a sequence diagram, a message represents a service request. True. ... In a sequence diagram, a message is considered to be an action that is invoked on the destination object. True.

A sequence fragment is represented as a box, called a combined fragment, which encloses a portion of the interactions within a sequence diagram The fragment operator (in the top left cornet) indicates the type of fragment Fragment types: ref, assert, loop, break, alt, opt, neg Massimo Felici Sequence Diagrams c 2004-2009

The first diagram is a sequence diagram and the second is a collaboration diagram. The Sequence Diagram. The sequence diagram has four objects (Customer, Order, SpecialOrder and NormalOrder). The following diagram shows the message sequence for SpecialOrder object and the same can be used in case of NormalOrder object. It is important to ...

You can put the part of the flow that is continued only if the break condition is not met inside the opt combined fragment. The opt fragment should have a guard that is opposite to the condition at which the flow should stop. If any additional actions should happen in case of a break, they should be put after the opt combined fragment.

i don't think it's appropriate for a sequence diagram. the sequence diagram should describe a sequence (as the name hints). in my opinion it should be a sequence from a use case. if the use case has extensions (these represent control flow), then make one sequence diagram for each extension. let the programmer combine this with state diagrams, and then decide if an if-statement is the correct ...
