The Origin of UML The goal of UML is to provide a standard notation that can be used by all object-oriented methods and to select and integrate the best elements of precursor notations. UML has been designed for a broad range of applications. Hence, it provides constructs for a broad range...
在软件工程中,类图在统一建模语言(UML)中属于静态结构图,它通过展示系统的类的属性、操作(或方法)还有对象之间的关系的方式方式描述了系统的结构。 Purpose of Class Diagrams(类图的目的) Shows static structure of classifiers in a system 显示系统的中的分类器的静态结构 Diagram provides basic notation for othe...
BPMN 2.0 is part of the OMG “triple crown” of process improvement standards, which also includes case management model notation (CMMN) and decision model notation (DMN). The standards differ from the unified modeling language (UML) used in software design. OMG’s BPMN 2.0.1 specification has...
In object-oriented design, there is a notation of visibility for attributes and operations. UML identifies four types of visibility: public, protected, private, and package. The +, -, # and ~ symbols before an attribute and operation name in a class denote the visibility of the attribute ...
expressed in UML. The model for Aphid appears in the left side of Figure 2. UML's diamond notation denotes ownership instead of aggregation -- ownership is a more rigorous relationship than aggregation, as each object (except 由于蚜虫被写用一种面向对象的语言,它的信息模型用UML最容易地被表达。
Standardized:Process models typically use one of two standardized styles of graphical business process notation:business process modeling notation (BPMN)—also called business process model and notation—or unified modeling language (UML). Within these notation systems, certain visual elements have universal...
given a value (or expression) we cannot find the cell of which those are attributes. Visibility of Class attributes and Operations In object-oriented design, there is a notation of visibility for attributes and operations. UML identifies four types of visibility:public,protected,private, andpackage...

Composite Structure Diagram is one of the new artifacts added to UML 2.0. A composite structure diagram is a UML structural diagram that contains classes, interfaces, packages, and their relationships, and that provides a logical view of all, or part of a software system. It shows the ...
Graphically, a component diagram is a collection of vertices and arcs and commonly contain components, interfaces and dependency, aggregation, constraint, generalization, association, and realization relationships. It may also contain notes and constraints. RelationshipsNotation Association: An association sp...
