The diagram emphasizes events that cross the system boundary from actors to systems. A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD): A regular version of sequence diagram describes how the ...
The interaction overview diagram is similar to the activity diagram, in that both visualize a sequence of activities. The difference is that, for an interaction overview, each individual activity is pictured as a frame which can contain a nested interaction diagram. This makes the interaction overview diagram useful to "deconstruct a complex ...
The UML sequence diagram shows the run-time interactions: In this example, the Sender object calls handleRequest() on the receiver1 object (of type Handler). The receiver1 forwards the request to receiver2, which in turn forwards the request to receiver3, which handles (performs) the request.
Communication diagrams show much of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other. Communication diagrams show which elements each one interacts with better, but sequence diagrams show the order in which the interactions take place more clearly.
A sample DSM with 7 elements and 11 dependency marks. The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix (PSM), incidence matrix, N 2 matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the ...
The diagram would have actors on the left side, with arrows indicating the sequence of actions and interactions between systems and actors as described. Sequence diagrams should be drawn for each use case to show how different objects interact with each other to achieve the functionality of the use case.
Action sequence-Action state-Action steps-Activation - the time during which an object has a method executing. It is often indicated by a thin box or bar superimposed on the Object's lifeline in a Sequence Diagram; Activity diagram - a diagram that describes procedural logic, business process or work flow. An activity diagram contains a number ...
A message sequence chart (or MSC) is an interaction diagram from the SDL family standardized by the International Telecommunication Union. The purpose of recommending MSC (Message Sequence Chart) is to provide a trace language for the specification and description of the communication behaviour of system components and their environment by ...
