How to Create a Data Flow Diagram

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO

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 PRO diagramming and vector drawing software and Data Flow Diagram solution.

Types of Flowcharts

A Flowchart is a graphical representation of process, algorithm, workflow or step-by-step solution of the problem. It shows the steps as boxes of various kinds and connects them by arrows in a defined order depicting a flow. There are twelve main Flowchart types: Basic Flowchart, Business Process Modeling Diagram (BPMN), Cross Functional Flowchart, Data Flow Diagram (DFD), IDEF (Integrated DEFinition) Flowchart, Event-driven Process Chain (EPC) Diagram, Influence Diagram (ID), Swimlane Flowchart, Process Flow Diagram (PFD), Specification and Description Language (SDL) Diagram, Value Stream Mapping, Workflow Diagram. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design a Flowchart of any of these types. This solution offers a lot of special predesigned vector symbols for each of these widely used notations. They will make the drawing process of Flowcharts much easier than ever. Pay also attention for the included collection of ready Flowchart examples, samples and quick-start templates. This is business process improvement tools. If you are looking for MS Visio for your Mac, then you are out of luck, because it hasn't been released yet. However, you can use Visio alternatives that can successfully replace its functions. ConceptDraw PRO is an alternative to MS Visio for Mac that provides powerful features and intuitive user interface for the same.

Activity Network Diagram Method

Activity Network Diagram - This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Seven Management and Planning Tools solution from the Management area of ConceptDraw Solution Park. This sample shows the PERT (Program Evaluation Review Technique) chart of the request on proposal. A request for proposal (RFP) is a request of the company or the organization to potential suppliers to submit the business proposals for service or goods that it is interested to purchase. The RFP is represented on the initial procurement stage and allows to define the risks and benefits.

Interactive Voice Response Network Diagram

ConceptDraw solution Computer and Networks provides Interactive Voice Response samples, templates and library of 35 vector stencils for drawing the IVR network diagrams. Use ConceptDraw PRO diagramming and vector drawing software enhanced with solution Computer and Networks to visualize the logical and physical structure of IVR systems for inbound and outbound call centers and voice mail systems.

Network Diagram Software Backbone Network

ConceptDraw - Perfect Network Diagramming Software with examples of Backbone Network Diagrams. ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Backbone Network diagrams.

Local area network (LAN). Computer and Network Examples

Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage. ConceptDraw PRO is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects. ConceptDraw PRO is the ideal choice for network engineers and network designers who need to draw fast and easy Local Area Network Diagrams, for IT specialists, developers and other IT professionals which need to visualize the communication schemes of LAN and visually document the LAN's physical structure and arrangement in houses, offices and other buildings. Ready-to-use vector objects from Computer Network Diagrams solution will help you design LAN diagrams in minutes.

Internet Group Management Protocol (IGMP). Computer and Network Examples

The Internet Group Management Protocol (IGMP) is a communication protocol of the multicast transfer data in the IP networks. IGMP is used by routers and IP hosts for organizing the network devices in groups. This example was created in ConceptDraw PRO using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. It shows the architecture of the network for delivering a multicast service using IGMP.

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 PRO 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).

Microsoft Azure

Microsoft Azure is widely used cloud platform which was created by Microsoft and now is managed by Microsoft datacenters in 19 regions of the world, and has a wide set of benefits and features. ConceptDraw PRO diagramming and vector drawing software extended with Azure Architecture Solution from the Computer and Networks area of ConceptDraw Solution Park is the best for designing various pictorial infographics, illustrations and materials showing the possibilities and work of Microsoft Azure Cloud System and Azure services.

Hotel Service Process
