Example of DFD for Online Store (Data Flow Diagram)

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw DIAGRAM enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

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.

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).
