Hotel Network Topology Diagram

Network topology is a layout of various elements of computer network, such as nodes, links, routers, etc. It is a network topological structure which can be depicted logically or physically. Physical topology shows the physical location of network's components and cable connections between network nodes. Logical topology describes the data flows, the circulation of signals in physical topology. The physical and logical topologies for two networks can be identical, while their physical interconnections, the distances between nodes, transmission rates, and/or signal types may be differ. ConceptDraw DIAGRAM with Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park lets you design physical and logical network topology diagrams for wireless and wired computer communication networks located in various premises, including the hotels. You can easy design Hotel Network Topology Diagram, diagrams depicted LANs and WLANs, and also any of eight basic topologies (Point-to-point, Star, Bus, Mesh, Ring, Tree, Hybrid, Daisy chain).

Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design. The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.

Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.

Data Flow Diagram Examples

Data flow diagrams (DFDs) are effective to reveal relationships among the various components in a program or system. This type of diagrams is an important and useful technique for modeling an information system, its process aspects, for showing a system as a single high-level process. DFD lets illustrate the flow of data, how the input data are transformed to output results across the sequence of functional transformations. DFD consists of four major components: entities, processes, data stores, data flows. When you need to draw a Data Flow Diagram the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Data Flow Diagrams solution will be helpful for you. Providing numerous collection of Data Flow Diagram examples, samples, templates and ready-to-use vector DFD symbols, Data Flow Diagrams solution ensures you with all needed tools for easy designing DFDs according to Gane-Sarson or Yourdon-Coad notation on your choice. Any from offered predesigned DFD examples can become a perfect base for your own diagram.

Data Flow Diagram Example

ConceptDraw DIAGRAM extended with Data Flow Diagrams solution is the best diagramming and vector drawing software for quick and easy designing the Data Flow Diagram Example of any complexity.

Pyramid Chart Examples

Pyramid Charts and Triangle Diagrams are used to visually structure the topics and progressively order the quantitative data. They allow to illustrate hierarchical structure of the topics, proportional, interconnected and containment relations among the topics. The multilevel Pyramids and Triangle diagrams are constructed oriented up or down and divided into several horizontal slices. They are effectively used to represent marketing strategies, social strategies, information systems, market value, etc., to illustrate presentations, websites, documents, reports in business, finances, sales, management, marketing, media, training, consulting, and many other fields. To maximize the efficiency in drawing the Pyramid Charts, use the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Pyramid Diagrams solution from Marketing area, which contains the set of Pyramid Chart examples, samples, templates and vector design elements of triangular diagrams and pyramids with different quantity of levels for various needs.

Types of Flowchart - Overview

When designing a process or an instruction in clear and understandable way, you should consider creating a flowchart. You can avoid spending a lot of time understanding complex concepts as they get clear with different diagrams. The flowcharts are very popular diagram type, they are useful at different fields from the description business processes to the presentation of cooking recipes. Basic Flowchart, Business Process Modeling Diagram, Process Flowchart, Cross Functional Flowchart, Procedure Flowchart, Data Flow Diagram, IDEF Flowchart, SDL Diagram, Workflow Diagram, Document Flowchart, Program Flowchart, Value Stream Map, System Flowchart, Highlight Flowchart, Sales Flowchart are the main types flowchart. The ConceptDraw DIAGRAM is one of the professional applications which has great advantages and using which you can create different types of Flowcharts easy and fast. Try to draw an illustrative and comprehensible diagram in ConceptDraw DIAGRAM describing the processes instead of writing complex long text and make sure how it is convenient. Visio is expensive, and if you use it in a team environment, these costs are compounded. ConceptDraw DIAGRAM is an affordable alternative to Visio and luckily, it comes with a team plan. ConceptDraw DIAGRAM can import and export Visio files, so Mac users can collaborate with PC users stuck on Microsoft's software.

DFD Library — Design elements

Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park provides plenty of predesigned templates, samples and DFD vector design elements proposed by three DFD libraries. These DFD library objects are designed to help you effectively model the data flows and functional requirements for the business processes or systems, to design the Process-oriented models or Data-oriented models, Data flowcharts and Data process diagrams, Structured analysis diagrams and Information flow diagrams. There are two different notations used to draw the Data Flow Diagrams (Yourdon & Coad and Gane & Sarson). These notations define the different visual representations for the processes, data stores, data flows, and external entities. ConceptDraw DIAGRAM software provides you with possibility of designing professional-looking Data Flow Diagrams, DFD Models, Data Flow Process Diagrams using any of these notations. Simply drag the predesigned DFD flowchart symbols from the appropriate library and connect by arrows depicting the data flow from one step to another.
