Flowchart symbols

Introduction to Flowchart Symbols

A flowchart is a graphical representation of different actions and steps. It is commonly used to present the flow of algorithms, workflows, or procedures because it displays steps in a linear order. A flowchart typically illustrates the steps as different types of boxes, with arrows linking them in the proper order. Various flowchart designs are used to create various kinds of flowcharts. Each flowchart symbol has a distinct meaning and context in which it can be used. Knowing the basic symbols and what they mean will make it simpler, whether you want to read a flowchart or attempt to make one yourself. The series of actions or steps and the relationships between them are shown using lines and arrows. These are called Flowchart symbols.

List of Flowchart symbols

Here is the list of Flowchart symbols mention below

1. Branch and Control of Flow Symbols

Terminator

The Oval shape / Pill shape represents the start or endpoint of the system. It contains the “Start” or “End” word.

Process or action

A box used to describe a single action or step or a whole sub-action within a larger process.

Decision

The Diamond Shape Indicates branching or decision points. From various points on the diamond, lines illustrating various decisions arise.

Connecting lines

The Arrow Shape  Use this symbol to link together various elements to demonstrate how the shapes relate to one another.

Yes/No Decision Point

It indicates a sequence in the process where the end-user selects an answer, such as “yes-no” or “true-false,” and then branches to various sections of the flowchart.

On-Page Reference

It used to indicate connect separate processes on the same page of the process.

Off-Page Reference

It would contain a letter inside. It represents that the flow starts on another page with a matching symbol containing the same letter.

Merge Symbol

It represents multiple systems or paths that are merged into a single one.

Extract Symbol

It represents multiple systems or paths that are merged into a single one.

OR Symbol

It represents the process flow continues in more than two branches.

Summing Junction

It represents a point in the flowchart where several branches merge into a single process.

Control Transfer

When certain conditions are satisfied, a step proceeds to a step other than the next step.

Annotation Symbol

It represents additional information about a step in the process.

2. Process/Operation Symbols

Sub Process Symbol

A series of activities within a larger and more complex procedure, routine, or module that execute particular tasks.

Predefined Process

It demonstrates a series of steps that form a complex process described elsewhere in the drawing, usually on a different page.

Delay

It indicates a delay in the process.

Preparation

Indicates the set-up to another step in the same process.

Manual operation

This indicates a process step that should be conducted manually instead of automatically.

Parallel Mode

It is also known as “Concurrent operation.” Two or more parallel processes or procedure phases are indicated.

3. Input and Output Symbols

Data (Input/Output)

The Parallelogram Shape Indicates whether data is entering or exiting the process from the outside.

Document

This shape represents a printout, like a report or a document.

Multi-Documents

It illustrates multiple documents in the system.

Display

It represents where the information is displayed in a process.

Manual Input

This is a process step where an operator or user is asked to manually enter data.

Card

Paper Tape

 

It specifies the data is stored on page tapes. This symbol is also no longer frequently used.

Loop Limit Symbol

 

It denotes the process at which a loop should stop.

Subroutine

 

A set of actions that execute a particular task within a broader mechanism is denoted by this symbol.

4. Data and Information Storage Symbols

Stored Data

It is also called a data storage symbol. This specifies where data or information is stored.

Database

It indicates a list of information or data with a consistent structure that can be searched and sorted.

Internal Storage

this symbol denotes the information or data is stored in memory during the execution of a program.

Sequential Data

Represents data that can be accessed in sequential order. The shape is meant to resemble a reel of tape.

5. Data Processing Symbols

Collate

Specifies a process step that organizes information or data into a standard format.

Sort

It indicates the arrangement of documents, data, or materials in a specific order.

Conclusion

The majority of the flowchart symbols in this article are for very particular purposes, as in a data flow diagram for computer programming.  Simple flowchart symbols are used advanced for the expertise, and the diagram is being created with a  group with similar knowledge. I hope you will find this article to create flowcharts.
