This chapter provides tutorial examples on UML sequence diagram and notations. Topics include introduction to UML sequence diagram; graphical notations to describe object lifeline, communication messages, execution specification, sequence frame, etc.What...
UML Sequence Diagrams are designed so that they can depict a timeline. On the top, you can see the beginning, and then the diagram flow descends downwards to mark the sequence of all interactions in the system. These interactions and objects have some symbols and notations that are used to ...
Basic Sequence Diagram Notations Class Roles or Participants Class roles describe the way an object will behave in context. Use the UML object symbol to illustrate class roles, but don't list object attributes. Activation or Execution Occurrence ...
The complete diagram header for a sequence diagram is as follows: sd [interaction] interaction name [diagram name] The diagram kind for a sequence diagram is sd. and the model element type can only be interaction. Figure 10.1 shows a sequence diagram with examples of many of the symbols. ...
Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & ...
Entity Relationship Diagram Symbols→When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database proje...
In order to efficiently generate hopping sequences for them, the hopping sequence described with reference to FIGS. 3 and 4 may be used as the hopping sequence for the control channel. As shown in FIG. 7, since one slot includes seven symbols, the hopping sequence for the control channel ...
The model is expressive because its structure enables it to capture simultaneously the two aspects of sequence behavior, i.e., sequential symbol pattern and duration between symbols. Also, the model has flexibility of adjusting its sensitivity on either aspect to match application requirements. In ...
The aforementioned FSM is used to discriminate between acceptable and unacceptable strings of plaintext symbols that can be obtained by examining various key bit sequences. Accordingly, perfect security amounts to maintaining the size of the acceptance set unchanged, and consequently, the uncertainty ...
Conventions and notations: The notation P n for the geometric types consist of a prefix P and a number n. The number n runs from 1 to 90 and is sufficient to determine the type. The prefix P runs from A to F and encodes only some geometric information, which is defined as follows: ...
