The meaning for each symbol offered by ConceptDraw gives the presentation about their proposed use in professional Flowcharts for business and technical processes, software algorithms, well-developed structures of web sites, Workflow diagrams, Process flow diagram and correlation in developing on-line ...
or a relation between two categories of workers, or any similar relationship. By default, both elements in an Association are equal, and are aware of each other through the Association. An Association can also be a Navigable Association, meaning that the source end of the association is aware...
A negative trace indicates violated constraints, meaning the system has failed. A duration constraint is represented by a graphical link between the time interval and the element it constrains.Time ConstraintA time constraint represents a time interval and indicates whether the constraint is satisfied ...
Because OCL is a modeling language in the first place, not everything in it is promised to be directly executable. Formal Language − OCL is a formal language where all constructs have a formally defined meaning. The specification of OCL is part of the UML specification. OCL is not ...
The string consists of a name (the tag), a separator (the symbol =), and a value (of the tag) as shown in the Figure below: You can specify just the value if its meaning is unambiguous, such as when the value is the name of the enumeration. Usage of Tagged Values One of the ...
Be independent of particular programming languages and development processes. Provide a formal basis for understanding the modeling language. Encourage the growth of the OO tools market. Support higher-level development concepts such as collaborations, frameworks, patterns and components. ...
Exiting via a FinalState or by a group Transition has the same meaning as for ordinary composite States. 通过终止状态退出或者通过一组迁移退出具有相同的含义,这一点和通常的组合状态一样。 参考资料: 《OMG Unified Modeling Language TM (OMG UML) Version 2.5》 ...
Of course, the improvements in behavioral modeling also had an effect on the process view in the systems integration model. A significant improvement is the ability to add input and output parameters to activities. Hardly any changes were made in the area of static views, meaning the design of...
Activity diagrams may be regarded as a form of flowchart. Typical flowchart techniques lack constructs for expressing concurrency. However, the join and split symbols in activity diagrams only resolve this for simple cases; the meaning of the model is not clear when they are arbitrarily combined wi...
UML as a programming language This goes directly from a UML model to executable code (not just portions of the code as with forward engineering), meaning that every aspect of the system is modeled. Theoretically, you can keep your model indefinitely and use transformations and code generation ...
