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.

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.

Closed-circuit television (CCTV) uses cameras and monitors to carry out video surveillance. Unlike broadcast television this system has only local signal. It is a feature of almost every video camera, yet CCTV is mainly a system for visual control of certain areas such as banks, airports, supermarkets, and other places for security reasons.
Developing and installing CCTV system is a time-consuming process. It also requires certain knowledge and skills. ConceptDraw is a solution of setting video cameras rationally. You can achieve two aims at once: CCTV Design Tool saves your time and your money and helps you make professional video surveillance system.
Creating CCTV system diagrams is quick and easy with ConceptDraw DIAGRAM diagramming software enhanced with Audio, Video, Media solution from ConceptDraw Solution Park. It contains library of vector cliparts of video and TV devices and different digital gadgets for drawing this kind of diagrams.

The UML Diagrams are widely used by software developers and software engineers. They can draw the UML Diagrams manually on the paper, but it is incredibly convenient to use the special UML diagramming software. The UML diagramming software allows you to draw the UML Diagrams in a few minutes.
If you are related with chemistry in you work or education activity, you need often draw various illustrations with chemistry equations. ConceptDraw DIAGRAM diagramming and vector drawing software offers you the Chemistry solution from the Science and Education area.
Chemistry solution provides the Chemical Drawings Library with large quantity of vector chemistry equation symbols to help you create professional looking chemistry diagrams quick and easy.
If we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon.
This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.
