UML Class Diagram. Design Elements

UML Class Diagram is a type of Structure Diagrams that shows the classes of a system, attributes, operations, and the relationships between them.

Class Diagram is one of important types of UML Diagrams. UML Class Diagrams are used for static modeling of the system, for data modeling, for conceptual modeling of the application, and for modeling of the system dictionary.

On the Class Diagram, Classes are represented as boxes that consist of three parts: name, attributes of the class, and operations or methods.

Use the following notations to set the visibility of a class member: Public (+), Private (-),
Protected (#), Derived (/), Static (_), Package (~). Notation must be placed before the name of class member.

There are a few types of associations between objects and classes on the Class Diagrams.

Bi-directional associations are represented by a line between two classes, it is default connection between classes.

Uni-directional associations are represented as the unbroken lines with an open arrowhead.

Aggregation is an association with the relation between the whole and its parts, and is represented as empty diamond on the Class Diagram.

Composition is a strong variant of aggregation, represents on as filled diamond.

Generalization or inheritance is when a child object or class assumes all properties of his parent object or class, is represented as empty triangle.

There are four notations: 0..1, 1, 0..*, 1..*, that indicate the multiplicity of associations.

The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.

To design your own Class Diagram use the UML Class Diagram library.

UML Class Diagram library contains 39 shapes:

  • Class

Entity-Relationship Diagram (ERD) with ConceptDraw DIAGRAM  →

Database structures are usually described by ER-diagrams which represents entities as boxes with lines-connections between them. You can create any entity-relationship diagram (ERD) by means of ConceptDraw DIAGRAM using ready-to-use templates and special libraries containing all the needed symbols and shapes. Creating a model for your database from now on can take just a few minutes. ERD (entity relationship diagram) designed to show the logical structure of databases. It intended to depict the relationships between data components (entities). ERDs are a popular tool for software engineers and architects. Using ERD they can manage the every aspect of database design. Also ERD can be used as guidelines for testing and communications before software release. This diagram represents the file reference system of the WordPress web platform. Because entity relationship diagrams have such a broad application area through the prevalence of database technology, it can be applied for a wide range of users.Entity-Relationship Diagram (ERD) <br>with ConceptDraw DIAGRAM  *

Multi Layer Venn Diagram. Venn Diagram Example →

To visualize the relationships between subsets of the universal set you can use Venn diagrams. To construct one, you should divide the plane into a number of cells using n figures. Each figure in the chart represents a single set of, and n is the number of represented sets. Splitting is done in a way that there is one and only one cell for any set of these figures, the points of which belong to all the figures from the set and do not belong to others. The plane on which the figures are represented, is the universal set U. Thus, the point which does not belong to any of the figures, belongs only to U.Multi Layer Venn Diagram. <br>Venn Diagram Example *

Hotel Network Topology Diagram →

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network. On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.Hotel Network Topology Diagram *
