Principles of System Design

. The principle of autonomy and controllability. Network security and confidentiality are related to the sovereignty and security of a country, so network security products cannot rely on foreign products. 7. The principle of safety and value. The design of the network system is limited by funds.

The overall design of the system should be based on the design idea of system engineering, so that the developed system can meet the overall requirements of scientific, rationalization and economy.Generally, the following basic principles are followed.

The principle of flexibility and variability. Flexibility refers to the ability of the system to adapt to changes in the external environment. Whether a system can play a role and have strong vitality depends to a large extent on whether it is acceptable to management.

Feasibility principle The feasibility principle refers to the fact that in the process of planning and design of the logistics system, each planning element must meet the established resource constraints. That is to say, the planning and design of the logistics system must take into account the existing disposable resources and must meet their own actual situation, whether technically, It can still be achieved economically.

In the practice of system design, these two methods are often used together. Phase development principle The system framework and data structure are comprehensively designed, and the specific functions are realized in stages.

Comprehensive principle: The design of mechatronics system needs to consider factors such as mechanical, electrical, electronic and computer to ensure the comprehensiveness of the system.

What is the concept of system design?

1. System design is developed by the information system.In the second stage, its main goal is to design a system solution that meets the needs of users according to the requirements specifications obtained in the system analysis stage.

2. The overall design of the system is the design of global problems, that is, the design of the overall treatment scheme of the system, also known as outline design. The overall design of manufacturing system engineering includes: market research, technical specification preparation, preliminary design, detailed design, product manufacturing, etc.

3. System design is the physical design stage of a new system. According to the logical model and functional requirements of the new system determined in the system analysis stage, a scheme that can be implemented in the computer network environment is designed under the environmental conditions provided by the user, that is, to establish a physical model of the new system.

DesignThe composition of the system

The computer system is composed of a hardware system and a software system, among which the software system is composed of system software, support software and application software. 2 The computer system is composed of hardware and software. Hardware includes: input and input equipment. The software includes: system software and application software. Computer software generally refers to all kinds of programs and files.

Database design: determine the database type and structure that the system needs to use, including table design, field definition, index creation, etc. Interface design: Define the interface between the system and the external system or user interaction, including the format, protocol and interface security requirements of input and output data.

Computer hardware: It is a general term for various computer parts and equipment composed of electronic, mechanical and optoelectronic components in the computer system. It is the material basis for computers to complete various tasks.It refers to the actual device in the computer system, which is the visible and tangible physical components that make up the computer. It is the "body" of the computer.

The difference between the outline design and the detailed design of the system_The detailed design of the system mainly includes

1. The difference between the outline design and the detailed design Outline design realizes soft The overall design of the piece, module division, user interface design, database design, etc.; the detailed design is based on the module division made by the outline design, to realize the algorithm design of each module, realize the refinement of user interface design, data structure design, etc.

2. The differences between outline design and detailed design are as follows: the main task of outline design is to convert the system extension use case diagram obtained from requirements analysis into software structure and data structure.

3. Hierarchy and abstraction: Outline design is a high-level design of the system on the basis of requirements analysis, paying attention to the overall structure, module division and relationship of the system. The outline design focuses on the interaction between the functions and modules of the system.

4. Outline design is to design the structure of the software, including the composition of the module, the hierarchy of the module, the call relationship of the module, the function of each module, etc.

5. The outline design mainly explains the goals and construction principles of the system, the functional modules of the system and the database outline design (what are the table names). The outline design is aimed at designers and users. Simply put, users can also understand it without requiring too much details. It is a technical response to the needs of users, which is the gap between the two. A bridge that is connected.
