Explanation:
What do flowchart symbols mean?
Which flowchart shape should you use? If you are new to flowcharting, the large number of shapes can be intimidating. This page should help in making your decision. Most charts can be drawn with the first five basic flowchart shapes listed. The others are optional and often only confuse people.
Circle
Circles represents data in most flowchart diagrams. With GIS circles are used to distinguish data input to a process and data that result from processing. It is convenient to use different colors to identify various states of data: input, temporary, output, final product, and the like. ESRI's Model Builder also uses circles in the case of processes that require constants or other input other than spatial data
Lines with Arrows
You read a flowchart by following the lines with arrows from shape to shape. The lines with arrows determine the flow through the chart. Flowcharts are usually drawn from top to bottom or left to right. Numbering shapes is optional. Numbering is helpful if you have to refer to a shape in a discussion. Numbering does not determine the flow of control. That is determined by the lines with arrows. If two lines cross, you ignore the perpendicular line and continue following the line to the next shape. If there may be confusion as to the path, you can insert a bridge or crossover, which is a little bump on crossed lines.
Rectangle
In most flowcharts, the rectangle is the most common shape. It is used to show a process, task, action, or operation. It shows something that has to be done or an action that has to be taken. The text in the rectangle almost always includes a verb.
Decision
A decision asks a question. The answer to the question determines which arrow you follow out of the decision shape. Decisions can take place at points where results need to be evaluated before the process may continue. Another use can be in the case of conditional operations embedded in the flow.
Alternate Process
The rounded rectangle is sometimes used instead of the standard rectangle and can have the same meaning. However, it is also used as an alternate process. The lines associated with the alternate process are usually dashed. It allows you to specify a process in a sharp cornered rectangle and an alternate process in a rounded rectangle. Some people also use the rounded rectangle for an automated activity.
Manual input
This shape looks like a side view of a keyboard and often represents entering data into a computer via a keyboard
Manual Operation
The trapezoid shape represents a manual operation. That is any operation or adjustment that has to be done by hand rather than automatically.
Preparation
This shape was originally used by IBM programmers to set a switch, modify an index register, or initialize a routine. Currently you can use it to differentiate between steps that prepare for work versus steps that actual do the work. It is probably best not to use this shape at all.
Database
A cylinder represents a data file or database. This shape can also represent the magnetic disc itself. A hard drive is referred to as direct access storage since any sector on the drive can be accessed. Compared to the circle symbol for data input and output the database is best used to represent instances where collections of data are assembled in an organized manner like an ESRI geodatabase.
Comment
This shape was used to add a comment or additional descriptive text to a software flowchart. A dotted line should extend from the comment to the symbol it references. This shape is seldom used today.
Input / Output
A parallelogram is used to show input or output. Examples of input are receiving a report, getting an e-mail, getting an order, receiving data in some format, etc. Examples of output are generating a report, sending an e-mail, faxing a message, etc.
Document
A rectangle with a curved bottom represents a document or report.
Terminal
This shape tells you where the flowchart begins and ends. It shows the entry point of your flowchart and the exit point. It is useful to represent an end result of a flow process. It needs a suitably descriptive label to be useful.
Off-page connector
This shape means the flow continues on another page. A letter or page number in the shape tells you where to go. It is an alternative to using a circle.
