Data Flow Diagram

Data Flow Diagram (DFD) is the part of the Structured Systems Analysis and Design Methodology (SSADM), which is intended for information systems projection and analysis. Data Flow Diagrams allow graphically represent the data flows in information system and analyze the data processing during the structural projection. This type of diagrams lets visually show a work of information system and results of this work, it is often used in connection with human processes and can be displayed as Workflow diagram. Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution from Software Developmant area is ideal for designing professional looking DFDs, which can be then easily exported in various formats.

Data Flow Diagrams

The information system manages the flow of data introduced into the system. To graphically represent and document the flow of data through some information system is used a Data Flow Diagram (DFD). DFD is a way to visualize the flow of data or data processing, to clearly demonstrate what type of data or information is transferred, where they come from and where are sent. It lets to create an overview of the system, to depict the major steps, and effectively model the processes. DFDs are helpful for analyzing and modifying the business systems. Traditionally are used two notations for DFDs creation - Yourdon-Coad and Gane-Sarson. ConceptDraw DIAGRAM software offers a special Data Flow Diagrams solution from Software Development area, which enables to quickly and simply create professional Data Flow Diagrams including the data storage, data flows, external entities, functional transforms, control transforms and signals. Use the offered templates, samples and extensive range of libraries to design your own Data Flow Diagrams in minutes.

Bus Network Topology

Bus Network Topology is a network topology that represents one shared cable (called a bus or backbone) to which are directly connected all workstations or computers of the network. At the ends of the cable are situated the terminators for prevention the signal reflection. All workstations at Bus Network Topology have equal rights and transfer the information sequentially, one after another. The message sent by one of workstations is extended on all computers of the network and each computer checks to whom it is addressed, if for him, then processes it. Addition of new subscribers to the "bus" is quite simple, the failures of individual computers are not dangerous, and the lack of a central subscriber even more increases its reliability. Computer and Networks solution included to Computer and Networks area of ConceptDraw Solution Park offers templates, samples and numerous vector stencils libraries that can be used to effectively design different physical and logical network topologies diagrams for wireless and wired computer networks, including Bus Network Topology.

Pyramid Diagram

Pyramid diagram is a chart used to visualize the data in a hierarchical (pyramid-like) structure and depict the foundation-based relationships. Pyramid diagram looks like a triangle divided by lines into several sections (layers) and can be oriented up or down, and represented in 2D or 3D view. 2D Pyramid diagrams are a great way to illustrate the hierarchical structure, 3D Pyramids are equally good to represent the class stratification and hierarchy. ConceptDraw DIAGRAM diagramming and vector drawing software with included Pyramid Diagrams solution from Marketing area of ConceptDraw Solution Park is a powerful application which contains templates and library of vector design elements for instantly drawing three level Pyramid model, four level and five level Triangle charts. All predesigned objects are easy for changing color style and resizing according to your needs, and ConceptDraw documents with Pyramid diagrams can be easy exported in various formats for further using in marketing presentations, for effective analyzing hierarchy levels and illustration your data and ideas.

Data Flow Diagram Software

Data Flow Diagrams (DFDs) are successfully used when studying the business processes or systems that involve the transfer of data. They are a visual way to represent the data processing, to model and visualize the flow of data through a computer system and functional requirements for a designed system. They are the good business modeling tool to describe the business events and interactions, the physical systems involving the storage and transfer of data. ConceptDraw DIAGRAM supplied with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is a modern and powerful data flow diagram software. This solution offers large set of predesigned DFD vector objects, grouped to three libraries: Data Flow Diagrams, Gane-Sarson Notation, and Yourdon and Coad Notation. All they and also collection of DFD samples and built-in templates make a good base for ConceptDraw DIAGRAM users, providing them all conditions for easy creation the Data Flow Diagrams and Data Flow Models of any complexity.

Metropolitan area networks (MAN). Computer and Network Examples

Metropolitan area networks (MAN). Computer and Network Examples
A Metropolitan Area Network (MAN) is a great computer network located on the large geographical area or region. It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. MAN usually includes several buildings or even the whole city (metropolis). It is based on high data rate compounds using the fiber channels and other digital data transmission channels. MAN includes a lot of communicating devices, for its construction are used multiple routers, switches and hubs. MAN can combine together several Local Area Networks or Campus Area Networks located in different buildings within a city and provides the Internet connectivity for them. Solutions included to Computer and Networks Area for ConceptDraw Solution Park are the real godsend for those who want design Computer Network Diagrams, and among others the Metropolitan Area Network Diagrams. They offer the libraries with ready-to-use vector design elements, professional-looking examples, samples and templates.
