Flowchart
![Page 4: ppt on flow chart by harshid panchal with help of Sejal ma'm (git.org.in)](https://reader033.fdocuments.in/reader033/viewer/2022061203/547e532eb4af9fef158b55fd/html5/thumbnails/4.jpg)
A Flow chart
• Is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows.

Flow charts are used in analysing , designing , documenting or managing a
process or program in various fields.

Overview
• Flow chart are used in designing and documenting complex processes or programs.
• Like other types of diagrams , they help visualize what is going on and thereby help the people to understand a process , and perhaps also find flaws, bottlenecks , and other less-obvious features within it.
• There are many different types of flowcharts , and each type has its own repertoire of boxes and notational conventions.

Overview
• The two most common types of boxes in a flow chart are:
• 1) a processing step, usually called activity, and denoted as a rectangular box
• 2) a decision , usually denoted as a diamond.

TerminatorRepresented as circles , ovals or rounded rectangles, usually containing the word “Start” or “End” , or another phrase signalling the start or end of a process , such as “submit inquiry” or “receive product”.
Start / end

Arrows• Showing “flow of control”.
• An arrow coming from one symbol and ending at another symbol represents that control passes to the symbol the arrow points to .
• The line for the arrow can be solid or dashed.
• The meaning of the arrow with dashed line may differ from one flowchart to another and can be defined in the legend

processing
• Represented as rectangles.
• Use it to represent an event which is controlled within the process.
• Typically this will be a step or action which is taken.
• In most flowcharts this will be the most frequently used symbol.
• Examples: “ Add 1 to X”; “replace identified part”; “save changes” or similar.

Input / output
Represented as a parallelogram.
Represents material or information entering or leaving the system, such as customer order (input) or a product (output).
Example: Get X from the user; display X.

Decision
A decision or branching point. Lines representing different decisions emerge from different points of the diamond.

circle
Use it to represent a point at which the flowchart connects with another process.
The name or reference for the other process should appear within the symbol

• When dealing with a process flow chart, two separate stages of the process should be considered: the finished product and the making of the product. In order to analyse the finished product or how to operate the process , flow charts tend to use simple and easily recognizable symbols. The basic flow chart symbols below are used when analysing how to operate a process.

System flowchartshows how the data flows from source documents through the computer to its final distribution to the users. System flowcharts portray the interaction among
data, hardware and personnel.
