• 4、. The HS code reference for mineral exportsprinciple 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.

  3. Take advanced technology, practical system, reasonable structure, mainstream products, low cost and low maintenance as the principles of capital construction, and plan the overall structure of the system.

  

  The principles of system design include

What are the main contents of system design

The detailed design of the system includes the following: system structure design and subsystem division Division of system functional modules or subsystems (if there is or necessary, especially large-scale software systems).

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.

Data architecture; technical architecture; business architecture Business architecture is the foundation of IT architecture. It should describe the implementation of the whole platform or a product from the perspective of business and product.

What are the tasks and main tasks of system design

1. System design is an important stage in the development of management information system, and it is also the core of the whole development work. To realize the logical model proposed in the system analysis stage and Determine the structure of the new system. The system design stage is to solve the problem of 'what to do'.

2. The tasks to be completed in the system design stage include the following: designing the module hierarchy of the software system, designing the structure of the database, and designing the control process of the module. Hierarchy is an organizational structure of an operating system, which provides a model to isolate the functions of each layer of the operating system.

3. The main task of system design isOn the basis of system analysis, according to the requirements of the logical model, the overall design and specific physical design of the system are carried out scientifically and reasonably, and the necessary technical information is provided for the implementation of the next stage of the system. System design is the physical design stage of a new system.

What does the system architecture design include

1. Including network security, firewall, load balancing, gateway, service governance, development services, security services, and the technology stacks used by business modules.

2. In object-oriented design, what are the contents of system architecture design? The concepts in object-oriented programming mainly include: objects, classes, data abstraction, inheritance, dynamic binding, data encapsulation, polymorphism, and messaging. Through these concepts, object-oriented thinking has been concretely reflected.

3. The main content of system design System design is divided into overall structure design and detailed structure design. The overall structure design mainly solves the problems of subsystem division and confirmation, module structure design, network design and configuration scheme.

The principles of system design include

1, the principles 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.
