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:
classes of a system,
and the relationships between classes.

The following table represents notations that are used on the UML Class Diagrams:
Class represents a set of objects that have the same structure, behavior, and relationships with objects of other classes.
Attribute is a typed value that defines the properties and behavior of the object.
Operation is a function that can be applied to the objects of a given class.
Responsibility is a contract which the class must conform.
Interface is an abstract class that defines a set of operations that the object of the class associated with this interface provides to other objects.
Association is a relationship that connect two classes.
Aggregation is an association with the relation between the whole and its parts, the relation when one class is a certain entity that includes the other entities as components.
N-ary association represents two or more aggregations.
Composition is a strong variant of aggregation when parts cannot be separately of the whole.
Generalization ia an association between the more general classifier and the more special classifier.
Inheritance is a relationship when a child object or class assumes all properties of his parent object or class.
Realization is a relationship between interfaces and classes or components that realize them.
Dependency is a relationship when some changes of one element of the model can need the change of another dependent element.
Allows to define the properties of the dependency relationship between classes or classes and packages.
Allows to indicate the additional properties of association.
Multiplicity shows the quantity of instances of one class that are linked to one instance of the other class.
Package groups the classes and other packages.
Note is a textual explication.
Note connector is a connection between the note and elements.

Process mapping helps with sharing business results and reorganizing workflow. In almost every case, after creating a sales process flowchart the steps that are redundant become obvious for a manager. It's easy to find a flowchart examples that will help in developing one for your business.
This sales process flowchart consists of a sequence of steps that represent a simple sale process. Each step is shown graphically by a rectangle representing processing steps or an activity, or a diamond representing a decision. These rectangles are linked by arrows, that indicate the direction of the sales workflow. ConceptDraw Sales Flowcharts solution delivers a the full set of classical flowchart notation symbols, along with sales-related icons and pictograms.

ConceptDraw DIAGRAM compatible Mac OS X software extended with powerful Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park is one of the famous ER Diagram Programs for Mac. It gives the perfect ability to draw ER diagrams for visually describing databases with Chen's and Crow's Foot notation icons.
The first thing that usually comes to mind when talking about database models is ER-diagrams, and the ways to create them. The second most recognizable notation is the Crow’s Foot, which visually differs from Chen’s notation. Actually, it doesn’t matter which notation you’ll use for your entity relationship diagram (ERD), but the content is what matters.
When designing an Entity-Relationship Diagram one need to use a certain notated symbols that were developed and standardized especially for databases description. First of them - the Chen’s notation had a linguistic origin. It includes rectangle boxes to show entities that may be described as nouns, and the relationships between them described as verbs depicted in a form of diamond. Finally the Chen’s notation was simplified up to the Crow’s Foot notation. It represents a relationship as labeled line. It is precisely this notation is shown in the given figure. ConceptDraw DIAGRAM together with its Entity-Relationship Diagram (ERD) solution is designed to support professionals who deals with creating ER diagrams using the element of both - Chen’s and Crow's Foot notations.
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.

You can use many tools to create a representation of a system behavior or a scheme of objects relationships. Some of them are quite abstract and useless, and some, like UML tools help clarifying both the structure and the behavior of a system. There are various types of uml diagrams and tons of examples explaining the difference between them.
UML 2.2 specification has many kinds of diagrams. They are divided into two groups( structure and behavior diagrams). This class diagram shows the hierarchical structure of UML 2.2 specification. Class diagram - the most suitable tool for this task because it is designed to describe basic structure of a system. This diagram can be use as a visual aid for learning UML.
Use Case Diagram Taxi Service UML. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the work of the taxi service and is used by taxi stations, by airports, in the tourism field and delivery service.
While developing software, it is very important to have a visual model, because it helps to represent the logic and the architecture of an application. Experienced engineers use UML diagrams to denote relationships between classes and their instances. UML is a general language for a set of diagrams like deployment diagrams, object diagrams or use case diagrams.
This diagram represents UML class diagram used for a software system development using an object-oriented method. Class diagrams are categorized as static structure diagrams that depict the physical structure of a system. Class diagram divides a software system's structure into "classes". Classes are defined by the methods and variables of objects. UML Class diagram is used to depict relationships and source code dependencies between objects.
There are many ways to track the system in a critical situation. To model a system behavior, uml notation is widely used. Usually, an UML diagram consists of elements such as actor and a case.
This diagram represents the structure of UML notations. Unified Modeling Language (UML) is used in software engineering to depict graphically the software modeling process. UM Language uses graphic notations for developing models of object-oriented systems. These notations displays requirements, sub-systems, logical and physical elements, etc. We created this diagram using ConceptDraw DIAGRAM reinforced with Rapid UML solution. It can be helpful for students on software engineering, when learning UML.
