Entity Relationship Diagram Examples

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

CCTV Network Diagram Software

The CCTV is the process that carried out using the video cameras for transmitting the signal to the specific location, on the limited set of monitors. We are talking about the video cameras that are used for monitoring on such guarded objects as airports, banks, stores, military objects, etc. CCTV equipment is also used in the industrial installations, for surveillance in the public places, for recording the video on the digital video recorders.
The vector stencils library "Computer network" contains 51 symbols of computer network devices and equipment for drawing computer network diagrams.
"Network Mapping Software.
A number of software tools exist to design computer network diagrams / or generate visual maps of networks, servers, storage, services, data centers, and other peripherals. Broadly, there are two types of software tools - those that help create diagrams manually and those that generate them using automated / semi-automated approaches.
Type of Software.
(1) Manual - allows users to design and draw logical and physical topology diagrams by manually placing icons and connections.
(2) Automated - generate topology diagrams / maps by traversing the network and automatically discovering resident devices or by importing network data." [Comparison of network diagram software. Wikipedia]
ConceptDraw PRO is the software for manual design of computer network diagrams. The solutions of the Computer and Networks area in ConceptDraw Solution Park extend ConceptDraw PRO with vector stencils libraries, templates and examples for creating the computer network diagrams.
The symbols example "Computer network - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.
