The difference between the software system structure diagram and the program flowchart

1. The difference between the flowchart and the structure diagram is as follows: the flowchart is an excellent way to use graphics to represent the idea of the algorithm, because thousands of words are not as good as a diagram. Flowcharts are applied in assembly language and early BASIC language environments. THERE IS ALSO A PAD DIAGRAM, WHICH IS VERY SUITABLE FOR PASCAL OR C LANGUAGES.

2. A structure diagram is a component of a system, that is to say, which parts a system is composed of. For example, a person is composed of brain, hands, feet, etc. The flowchart is a step in which the system works in order. Of course, it can also be the steps to design a system.

3. The essential difference between the system structure diagram and the data flowchart: the two reflect different system functions. The data flow chart focuses on the control hierarchy and reflects the logical function of the system, that is, what the system can "do". The system structure diagram focuses on the data flow and reflects the physical model of the system, that is, how to gradually realize the total function of the system.

4. Program flowchart: Program logic describes the control flow in the program, that is, the execution order of the program and the conditions relied on by the execution sequence. The directed line segment in the diagram represents the control flow, from one processing to the next.

5. The structural diagram is mainly to more clearly reflect the internal organizational relationship, clarify the internal logical relationship, and standardize the respective functional parts at a glance and make them organized.System processing flowchart The system processing flowchart is drawn on the basis of the data flowchart of the new system.

How to draw a system structure diagram?

1. Just represent all parts of the system, including the accused object and the control device, in a box.

2. The first step: search for the "Yitu Diagram" software on the web page, or visit the online version of the Yitu Diagram web page and open the software.Start drawing. Step 2: Create a new system structure diagram. Just search for "system structure diagram" directly in the search bar, and then select a suitable template in the example template library below, and click to open and use.

3. Determine the structure and components: First, determine the components of the architecture to be drawn. This may include various modules, components, subsystems, services, etc. Determine the relationship and connection: Determine the relationship and connection of the components. This may include dependencies, interfaces, data flows, etc.

How to draw a system component block diagram

1. Step 1, open the Word document window and switch to the "function area". Click the "Shape" button in the "Illustration" group and select the "New Drawing Canvas" command in the open menu.Select the "New Drawing Canvas" command. Tips: You can also not use the canvas, but only insert the shape directly into the Word document page.

2. The drawing method of the system composition box is as follows: first, you need to write the text and add borders and background lines. Special symbols are inserted into the special symbols. Use the simulation of MATLAB software to draw a block diagram of the system.

3. Just represent all parts of the system, including the controlled object and the control device, in a box.

4. Create a new visio document and select the template you need. After selecting the template, the basic graphic of the corresponding template will appear in the right selection box. Take the block diagram of the closed-loop control system as an example to demonstrate the specific operation. First, put the required box on the drawing.

5. You can use some drawing software, such as Visio, PowerPoint, etc., to make a structure diagram of the computer system. During production, the basic framework of the computer system can be drawn first, including four main parts, including input device, output device, memory and central processor.

How to draw a future computer system structure diagram

The process of drawing this system structure diagram: determine system requirements and design goals, carry out system layering, and draw architecture diagrams. Determine the system requirements and design goals: it is necessary to clarify what tasks the system needs to complete, what functions it has, and what performance indicators the system needs to meet, etc.

You can use some drawing software, such as Visio, PowerPoint, etc., to make a structure diagram of the computer system.During production, the basic framework of the computer system can be drawn first, including four main parts, including input device, output device, memory and central processor.

On the "Drawing" toolbar, click "Insert Organization Chart or Other Diagrams". After selecting the first type of "used to display hierarchical relationships" in the "Illustration Library" that appears next, a hierarchical diagram will appear after clicking the "OK" button.

Excel to make an organizational chart. Preliminary preparation. First, we arrange departments and positions in Excel, and then insert an auxiliary column on the right for grading. Then click [View] and uncheck [Grid Line] to make the table more refreshing.

The concept of computer system hierarchy, the current comparisonThe consistent hierarchical structure of the computer system is shown in Figure 4 below, of which the left is the names of each level in the hierarchy, and the right is the representation of a programming language corresponding to different layers.
