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
Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM.
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.

This vector stencils library contains 195 cloud computing icons.
Use it to design cloud computing infographic and diagrams with ConceptDraw PRO software.
"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
Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.
