Flowchart

• Flowcharts for computer programming/algorithms
• How Flowcharts are used in numerous other fields

  • EDUCATION
  • SALES AND MARKETING
  • BUSINESS
  • MANUFACTURING
  • ENGINEERING
• Document Flowcharts


  Have the purpose of showing existing controls over document-flow through the components of a system. The chart is read from left to right and documents the flow of documents through the various business units.
• Data Flowcharts


  Show the controls governing data flows in a system. Data flowcharts are used primarily to show the channels that data is transmitted through the system rather than how controls flow.
• System Flowcharts


  Show the flow of data to and through the major components of a system such as data entry, programs, storage media, processors, and communication networks.
• Program Flowcharts


  Show the controls placed internally to a program within a system.
• Decision Flowcharts


  A diagram that helps make the decision between alternative courses of action that will lead to and effect a business decision.
• How to plan and draw a basic flow chart

  1. Define your purpose and scope

  2. Identify the tasks in chronological order

  3. Organize them by type and corresponding shape

  4. Draw your chart

  5. Confirm your flowchart
• START/ END


  Ovals or rounded rectangles are used to indicate the start and the end of a module or program
• Flowchart Lines


  Indicated by straight lines with arrows to show the direction of data flow. Used to connect blocks by exiting from one and entering another.
• Process Block


  The rectangle indicates a processing block, for such things as calculations opening and closing files, and so forth
• Initialization block


  Used for declaring / initializing variables needed to solve a certain process
• Input/Output block


  The parallelogram indicates input to and output operations
• Decision block


  The diamond indicates a decision. It has one entrance and exactly two exits from the block. A question or statement that gives you an answer of T/F or Yes/No
• Connectors


  The circle is used as a connection point between two sections of a flowchart that are not adjacent or closely located to each other
