How to Add Layers on PC

This article describes how to use ConceptDraw DIAGRAM Layers on PC. ConceptDraw DIAGRAM allows you to create as many layers, as you need. Layers in ConceptDraw DIAGRAM provide a way to assign specific properties of objects that have been assigned to the current layer. For example, you can turn on or off the visibility of the layer, Include or exclude the layer's objects when the diagram is printed. A blank document has the three layers by default. You can keep these default layers, or remove them or add your own.

Entity Relationship Diagram Symbols

Entity Relationship Diagram Symbols
The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.

How To Create CCTV Network Diagram

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.
The vector stencils library "Logical symbols" contains 49 logical symbols for drawing logical network topology diagrams.
"Logical topology, or signal topology, is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. The logical topology defines how the systems communicate across the physical topologies.
Logical topologies are bound to network protocols and describe how data is moved across the network. ... EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's token ring is a logical ring topology, it is physically set up in star topology." [Logical topology. Wikipedia]
The icons example "Logical symbols - 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.

"Cloud computing, also on-demand computing, is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers.
Cloud computing has become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability." [Cloud computing. Wikipedia]

How to Edit Grouped Objects on PC

ConceptDraw DIAGRAM allows one to group objects. Grouping shapes, pictures, or objects lets you style, format, rotate, and move them together, as though they were a single object. At the same time, you can edit each of them separately.

ERD Symbols and Meanings

ERD Symbols and Meanings
Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.
