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 DIAGRAM The ability easily create the SDL diagrams is made possible thanks to unique Specification and Description Language (SDL) Solution from the Industrial Engineering Area of ConceptDraw Solution Park. This solution extends ConceptDraw DIAGRAM with 2 libraries - SDL Connectors and SDL Diagrams that contain 71 predesigned SDL flowchart symbols.

SDL Diagrams Symbols Library

Example 1. SDL Diagrams Symbols Library

Turn attention for this enormous collection of predesigned vector objects which let design the SDL diagram of any complexity and degree of detailing in mere minutes.

SDL Connectors Symbols Library

Example 2. SDL Connectors Symbols Library

Try design your own SDL diagram in ConceptDraw DIAGRAM and make sure that is very easy! With powerful drawing tools of ConceptDraw DIAGRAM you don't need to be an artist, you can concentrate on your work and simply drag and use ready objects developed for you by professional designers.

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 DIAGRAM 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 DIAGRAM 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.

Activity on Node Network Diagramming Tool - Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project. This sample shows the Activity on node network diagramming method. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Seven Management and Planning Tools solution from the Management area of ConceptDraw Solution Park.Activity on Node Network Diagramming Tool *

Technical Drawing Software →

Every engineering project starts from a terms of reference document. The next stage of developing is a technical drawing, which requires using appropriate software. However, revisions and discussions about requirements are possible at any stage of development. This technical drawing demonstrates a schematic flow diagram of pulp reclaiming. This diagram of magnetite pulp reclaiming is created using ConceptDraw Chemical and Process engineering solution, The solution delivers more than 460 vector graphic icons and connectors. Generally, it is intended for designing process and instrumentation diagrams (P&ID) for chemical and process engineering. block flow diagrams (BFD), process flow diagrams (PFD) for chemical industry.Technical Drawing Software *

Types of Flowchart - Overview →

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps. Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.Types of Flowchart - Overview *
