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.
Example 1. Control Package Class Diagram
ConceptDraw DIAGRAM is designed to help you create UML diagrams quickly and easily. You'll get ready-made templates, examples and symbols as well as tools specifically designed to build the diagram you need.

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.

A model of a system is defined as a set of hierarchical diagrams representing the asynchronous process of data transformation from the moment it is input to the system to the moment it is output to the user. To demonstrate how a process transforms the initial data, you should design a data flow diagram using a DFD Library included in ConceptDraw DIAGRAM Solution Park. Start your diagramming experience now!
You can use this library of symbols related to data flow diagrams (DFD) to design data-oriented or process-oriented models along with data process diagrams. This vector objects library It is a part of ConceptDraw solution designed for data flow diagramming, along with corresponding samples and templates. A data flow diagram is a 2D flowchart that depicts the sequence of particular activities and operations operations and activities which is accompanied by the dynamic flow of some data.
The Ishikawa diagram, Cause and Effect diagram, Fishbone diagram — all they are the names of one and the same visual method for working with causal connections. Originally invented by Kaoru Ishikawa to control the process quality, the Ishikawa diagram is well proven in other fields of management and personal scheduling, events planning, time management. It is a chart in the form of a fish, whose head is a problem, the fins are variants for its causes.
To design easily the Fishbone diagram, you can use a special ConceptDraw DIAGRAM vector graphic and diagramming software which contains the powerful tools for Fishbone diagram problem solving offered by Fishbone Diagrams solution for the Management area of ConceptDraw Solution Park.
Planning a computer network can be a challenge for a junior specialist. However, knowing how to draw a computer network diagrams isn’t a rocket science anymore. There are a lot of special software for creating such diagrams with predesigned templates and examples.
The core for Network Fault Tolerance System presented here, is the equipment of Cisco. You can see here the certified Cisco equipment icons. Generally, ConceptDraw DIAGRAM libraries contain more than half of a thousand objects representing the standardized images of Cisco equipment. ConceptDraw solution for network diagramming is a great network diagramming tool for any level skills - from students to network guru.
Nowadays, more and more attention is paid to the comfort in the workplace, so that employees might be more motivated. Thus, it can be said with full confidence that office layout plays an important role for employees and influences company reputation. Many worldwide known companies have headquarter offices resembling more of a campus than of an office building.
Every organization has its own unique office design ideas, needs and requirements. Each of office position requires a certain type of person who has his own requirements, needs and habits. Office layout should be designed to facilitate its business function. The well-organized office space plays an important role in a workflow enhancement and productivity improvement. This office layout diagram demonstrates a typical cubical office layout. This diagram can be use as a template for cubicle office layout organization. This visual example can help shape ideas and design your office layout conception. You can start with adding your requested office furniture objects into your office floor plan. Plants help to create a healthy indoor environment. You can design an office space that totally fits your needs.
Engineering students usually have huge amount of homework. Learning how to develop a technical drawing is one of the necessary skills. Luckily, at the present time, there’s no need to draw it on paper, because there a lot of software tools for it.
This drawing represents the Bearing symbols library, that is the part of the ConceptDraw Mechanical Engineering solution. Bearings are the important components of any movable mechanism. The function of bearing is to align, guide, and support the moving parts in any mechanical construction. Usually they are located between moving and stationary parts, it works as a connection point between them. Using Mechanical Engineering solution and ConceptDraw DIAGRAM one can effortlessly draw engineering diagrams of any complexity.
The most worked out and commonly used methodology of business processes description is IDEF methodology. Besides business processes it allows to describe functional blocks, for example production and marketing. ConceptDraw lets creation of business processes description using IDEF0 and IDEF2 methods.
Software development flourishes nowadays. Students have tons of educational information and courses that would fit every taste. And it's no secret that knowing how to draw data flow diagrams is a useful skill for a future software architect. The diagrams help a lot in understanding how to storage data effectively and how data processes within a system.
This data flow diagram represents the model of small traditional production enterprise. It was created using Yourdon and Coad notation. The data flow diagram include four main objects: entity, process, data store and data flow. Yourdon and Coad notation uses circles to depict processes and parallel lines to represent data stores. Dataflows are shown as arrowed lines. They are labeled with the description of the data that move through them. Dataflow's role is to deliver the pieces of information. A process's function is to transform. the input data flow into output data flow. ConceptDraw Data Flow Diagrams solution contains the data flow diagram symbols of both Yourdon-Coad and Gane-Sarson notations and a set of handy templates to get started with DFD.
A workflow diagram is less general notation than a process flow diagram. Workflow as a term can apply to organizational process which involves people, resources, documents, sort of data, for instance; whereas a process is general collection of steps occuring in any sort of activity. That is why process flow diagram can be used as workflow diagram to describe business process, data flow or department interactions.
The fastest way to create a workflow diagram is using pre-designed workflow template. ConceptDraw DIAGRAM with the Workflow Diagrams solution delivers rich set of workflow diagram templates you may start from.
