SDL Flowchart Symbols

SDL diagram is a type of diagram which uses the graphical elements of Specification and Description Language (SDL) for designing the object-oriented diagrams, for modeling state machines in communication, telecommunication, aviation, automotive and medical industries, for creating specifications and descriptions of behavior, data, and inheritance for interactive real-time systems, reactive and distributed systems. SDL diagram is constructed of standard SDL elements (objects) which are designed according to International Telecommunications Union standards.

The SDL diagram consists of three building blocks: system definition which defines the major blocks (nodes) of the system such as clients and servers, block charts which show the details and process diagram which show the processing steps in each block. Arrows connect the objects and show the flow of control. The Start object shows beginning of the diagram.

Drawing the diagrams we try to find in help the powerful software and now we have the ConceptDraw PRO. The ability easily create the SDL diagrams is made possible thanks to unique Specification and Description Language (SDL) Solution from the Engineering Area of ConceptDraw Solution Park. This solution extends ConceptDraw PRO with 2 libraries - SDL Connectors and SDL Diagrams that contain 71 predesigned SDL flowchart symbols.

Follow the next few steps to create the SDL diagram:

  • add the objects to your diagram simply dragging them from the SDL Diagrams library to your document page and arrange them;

    Adding the Objects to SDL Diagram

    Example 4. Adding the Objects to SDL Diagram

  • add text to the objects - double-click an object to activate the text editing mode and type the text;

    Adding the Text to Objects

    Example 5. Adding the Text to Objects

  • connect the diagram objects using the connectors from the SDL Connectors library and add to text to connectors the same way you add text to objects, if needed.

    SDL Architecture

    Example 6. SDL Architecture

Each SDL diagram designed in ConceptDraw PRO can be then easy printed to share with colleagues, send via e-mail directly from the program, exported to various formats, including PPT, PDF, MS Visio, HTML, and many other popular graphic formats.

Specification and Description Language (SDL) Solution

Example 7. Specification and Description Language (SDL) Solution

Owing to the Specification and Description Language (SDL) solution and its powerful tools, the ConceptDraw PRO diagramming and vector drawing software is the best for easy drawing the SDL Diagrams to represent telecommunication systems, automotive systems, remote control systems, railway control systems, robotic systems, and more other.

Flow chart Example. Warehouse Flowchart

If you want to find a way to understand complex things in minutes, you should try to visualize data. One of the most useful tool for this is creating a flowchart, which is a diagram representing stages of some process in sequential order. There are so many possible uses of flowcharts and you can find tons of flow charts examples and predesigned templates on the Internet. Warehouse flowchart is often used for describing workflow and business process mapping. Using your imagination, you can simplify your job or daily routine with flowcharts. Warehouse flowcharts are used to document product and information flow between sources of supply and consumers. The flowchart provides the staged guidance on how to manage each aspect of warehousing and describes such aspects as receiving of supplies; control of quality; shipment and storage and corresponding document flow. Warehouse flowchart, being actual is a good source of information. It indicates the stepwise way to complete the warehouse and inventory management process flow. Also it can be very useful for an inventory and audit procedures.Warehouse Flowchart

Local area network (LAN). Computer and Network Examples

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN). Computer and Network Examples

Types of Flowcharts

A flowchart is a simple but very functional tool when it comes to understanding a workflow or to removing unnecessary stages from a process. When drawing flowcharts, keep in mind that there are four common types of flowcharts, like document flowcharts and data flowcharts that show control over a data or document flow over a system. To show controls on a physical level, use system flowcharts. In addition, to show controls in a program, you can draw a program flowchart. This flowchart diagram represents the piece of an article editing process, that involves the author and editor. It was created using the Basic Flowchart notation that consists from the basic flowchart symbols. The start and the end of the process are indicated with "Terminator" symbols. The "Process" symbols show the action steps consisting from making edits and searching for a compromise, when the author does not agree with the suggestions of the editor . The "Process" symbol is the general symbol in process flowcharts. The "Decision" symbol indicates a branching in the process flow. There are two branches indicated by a Decision shape in the current flowchart (Yes/No, Disagree/Agree). This basic flowchart can be used as a repeating unit in the workflow diagram describing the working process of some editorial office.Types of Flowcharts

Multi Layer Venn Diagram. Venn Diagram Example

To visualize the relationships between subsets of the universal set you can use Venn diagrams. To construct one, you should divide the plane into a number of cells using n figures. Each figure in the chart represents a single set of, and n is the number of represented sets. Splitting is done in a way that there is one and only one cell for any set of these figures, the points of which belong to all the figures from the set and do not belong to others. The plane on which the figures are represented, is the universal set U. Thus, the point which does not belong to any of the figures, belongs only to U.Multi Layer Venn Diagram

Basic Flowchart Symbols and Meaning

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data. This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.Flowchart Symbols and Meaning, workflow diagram symbols, process flow diagram symbols
