The meaning of various graphics in the flow chart

The meanings of the figures in the flow chart are as follows:

1, rectangle: generally used as the process to be executed, and the execution box is made in the program flow chart.

2. Rounded rectangle or oblate circle: indicates the start or end of the program, and is used as a start box or an end box in the program flow chart.

3. Oblique rectangle: Oblique rectangle is hardly used at ordinary times and can be defined by itself according to the situation. Or in other flowcharts, there are special meanings, which I don't know for the time being. I hope people of insight can give me some advice.

4. Diamond: indicates decision or judgment (for example, if. Then.Else), which is used as a decision box in the program flow chart.

5. File: represented as a file, which can be a generated file or a called file. How to define it depends on the actual situation.

6. Parentheses: notes or explanations, or conditional sentences. It is used when a generic process goes to a certain location, issues an execution instruction or performs a special behavior.

7. Semicircle: Semicircle is often used as a sign of process page jump and process jump.

8. Triangle: Control transmission, generally used in combination with line and drawing data transmission.

9. Trapezoid: generally used for manual operation.

10, ellipse or circle: if a small circle is drawn, it is generally used to indicate the flow direction of sequential data.

1 1, hexagon: indicates preparation, and most people use it as the beginning of the process, similar to the start box.

12, parallelogram: generally represents data, or some data processing. Or data entry.

13. Role: In the use case, who is the role that performs the operation in the simulation process? It should be noted that the role is not necessarily human, sometimes it is automatically executed by the machine, and sometimes it can simulate a system management.

14, data: refers to the database that stores the data of our website.

15. Picture: refers to a painting, or it is put into a picture, process or environment that has been painted.

What do the boxes in the flowchart mean?

1, rounded rectangles indicate "start" and "end".

2. Rectangular representation: action plan, joint work link.

3. The diamond indicates the problem judgment or determination (review/approval/review).

4. Represented by parallelogram: input and output.

5. The arrow represents the workflow direction.
