UML Class Diagram Notation

When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system . The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them. Read more

UML Class Diagram Constructor

UML Class Diagrams is a type of static structure diagram that is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code. It describes the structure of a system by showing the: classes of a system, attributes, operations, and the relationships between them. The Rapid UML Solution for ConceptDraw PRO includes the UML Class Diagram library that helps you to design the UML Class Diagram quick and easy. You can simply and quickly drop the ready-to-use objects from the library into your document to create the UML Class Diagram. Read more

The vector stencils library "UML class diagrams" contains 38 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"... classes are represented with boxes which contain three parts:
(1) The top part contains the name of the class. It is printed in Bold, centered and the first letter capitalized.
(2) The middle part contains the attributes of the class. They are left aligned and the first letter is lower case.
(3) The bottom part gives the methods or operations the class can take or undertake. They are also left aligned and the first letter is lower case. ...
To indicate a classifier scope for a member, its name must be underlined. ...
An association can be named, and the ends of an association can be adorned with role names, ownership indicators, multiplicity, visibility, and other properties. ...
Aggregation ... is graphically represented as a hollow diamond shape on the containing class end of the tree with a single line that connects the contained class to the containing class.
... graphical representation of a composition relationship is a filled diamond shape on the containing class end of the tree of lines that connect contained class(es) to the containing class.
... graphical representation of a Generalization is a hollow triangle shape on the superclass end of the line (or tree of lines) that connects it to one or more subtypes.
... graphical representation of a Realization is a hollow triangle shape on the interface end of the dashed line (or tree of lines) that connects it to one or more implementers. A plain arrow head is used on the interface end of the dashed line that connects it to its users.
Multiplicity ... representation of an association is a line with an optional arrowhead indicating the role of the object(s) in the relationship, and an optional notation at each end indicating the multiplicity of instances of that entity (the number of objects that participate in the association).
Entity classes ... are drawn as circles with a short line attached to the bottom of the circle. Alternatively, they can be drawn as normal classes with the «entity» stereotype notation above the class name." [Class diagram. Wikipedia]

The vector stencils library "Bank UML composite structure diagram" contains 10 shapes for drawing UML composite structure diagrams.
Use it for object-oriented modeling of your bank information system.
"The key composite structure entities identified in the UML 2.0 specification are structured classifiers, parts, ports, connectors, and collaborations.
* Part : A part represents a role played at runtime by one instance of a classifier or by a collection of instances. The part may only name the role, it may name an abstract superclass, or it may name a specific concrete class. The part can include a multiplicity factor, such as the [0..*] shown for Viewer in the diagram.
* Port : A port is an interaction point that can be used to connect structured classifiers with their parts and with the environment. Ports can optionally specify the services they provide and the services they require from other parts of the system. In the diagram, each of the small squares is a port. Each port has a type and is labelled with a name... in the diagram. Ports may contain a multiplicity factor...
* Connector : A connector binds two or more entities together, allowing them to interact at runtime. The connector is shown as a line between some combination of parts, ports and structured classifiers. The diagram shows three connectors between ports, and one connector between a structured classifier and a part.
* Collaboration : A collaboration is generally more abstract than a structured classifier. It is shown as a dotted oval containing roles that instances can play in the collaboration.
* Structured classifier: A StructuredClassifier represents a class, often an abstract class, whose behavior can be completely or partially described through interactions between parts.
An EncapsulatedClassifier is a type of structured classifier that contains ports." [Composite structure diagram. Wikipedia]

The part may only name the role, it may name an abstract superclass, or it may name a specific concrete class.

(2) Port : A port is an interaction point that can be used to connect structured classifiers with their parts and with the environment. Ports can optionally specify the services they provide and the services they require from other parts of the system. In the diagram, each of the small squares is a port. Each port has a type and is labelled with a name, such as "var", "indVar1", or "view" in the diagram. Ports may contain a multiplicity factor, for example.
Ports can either delegate received requests to internal parts, or they can deliver these directly to the behavior of the structured classifier that the port is contained within. Public ports that are visible in the environment are shown straddling the boundary, while protected ports that are not visible in the environment are shown inside the boundary. All the ports in the diagram are public, except for the view port along the right boundary of FibonacciSystem.
(3) Connector : A connector binds two or more entities together, allowing them to interact at runtime. The connector is shown as a line between some combination of parts, ports and structured classifiers. The diagram shows three connectors between ports, and one connector between a structured classifier and a part.

UML Notation

Unified Modeling Language (UML) is an open standard, the language of graphic description used for modeling objects in a field of software development and software engineering. It was created for definition, specification, visualization, designing and documenting software systems, as a unification of three object-oriented technologies Booch, OMT and OOSE, and uses the defined graphic notation for creating the visual models of object-oriented software systems. Description of UML consists of two parts, interactive and supplementing each other: UML semantics, which represents a certain metamodel, defines the abstract syntax and semantics of terms of object modeling with UML, and UML notation that is a graphic notation for visual representation of UML semantics. The powerful tools of the Rapid UML solution included to ConceptDraw Solution Park make the ConceptDraw PRO diagramming and vector drawing software the best for easy applying the UML notation when creating the visual models of object-oriented software systems and designing different kinds of UML diagrams.

UML Activity Diagram

UML Activity Diagram is a type of UML diagrams, which illustrates the business and operational step-by-step workflows of components within a system and shows the overall flow of control. UML Activity Diagram is constructed from a limited number of shapes, connected each other with arrows. The most important shape types are rounded rectangles, diamonds, bars, black circle, encircled black circle. The arrows represent the order in which activities happen and run from the start towards the end. ConceptDraw PRO software enhanced with Rapid UML solution is ideal for software designers and software developers who need to draw the UML Activity Diagrams and other types of UML diagrams. It is convenient to use the appropriate stencils of UML notation from the UML Activity library included to the Rapid UML solution of ConceptDraw Solution Park and containing a lot of specific vector UML objects. Use them to design your own UML Activity Diagrams, make them colorful and attractive with style tools of ConceptDraw PRO software. Read more
