What is system architecture

1. Brief description of computer system Architecture: Computer architecture refers to the general term for the components of computer theory and the basic working principles and theories of computers according to different attributes and functions. Among them, the theoretical components of computers are not only linked to an actual hardware, such as the storage part including registers, memory, hard disks, etc.

2. System structure refers to the various components of a system and the relationship and interaction between them. Hardware composition Hardware is an object in a computer system.The part, including the central processing unit (CPU), memory, hard drive, input and output devices, etc.

3. System architecture is a method of system modeling: among various views of system architecture, organizational views and behavior views are the most prominent and important. Therefore, to complete the synthesis of various views, we must first complete the unification of organization and behavior views.

4. It divides the software system into three basic parts: Model, View and Controller. The purpose is to achieve a dynamic and sustainable program design, simplify the subsequent modification and expansion of the program, and make the program a It becomes possible to reuse part of the code or function.

5. Computer architecture isThe attributes of the computer seen by the programmer, that is, the logical structure and functional characteristics of the computer, including the interrelationship between its various hardware and soft components.

system overall architecture

1. The overall structure of accounting information system consists of data module, running module and information module The block is composed of three modules.Data module: The data module is the core part of the accounting information system, which mainly collects, stores and maintains the accounting data of the enterprise.

2. The engine layer mainly includes the three-dimensional data engine TerDataMgr and the spatial data engine ArcSDE.

3. The overall architecture of the data center system. The data center plans the overall technical architecture, designs technical routes and methods from the top level to ensure that the network, data resources, application system, security system and other elements form an organic whole, and realize the linkage of enterprise (institutional) data resource management and Timely monitoring, summary and analysis of information.

4. 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.

5. The overall structure of the transmission and transformation equipment status monitoring system is "two-level deployment, three-level application" (see Figure 4-2). The overall framework can be divided into three levels: headquarters level (State Grid Corporation), network provincial level, and prefecture and municipal level.

6. The overall architecture of the system Complete the outline design of the aviation physical exploration database system according to the user's needs, determine the overall function of the software, explain the structure of the software, define the interface of the software, the system operating environment and the security policy. The overall architecture of the whole system development is constructed on the basis of the overall structure of the system and the analysis of requirements (Figure 4-1).

The concept of system architecture of system architecture

System architecture is a systemModeling method: Among the various views of the system architecture, the organizational view and behavior view are the most prominent and important. Therefore, to complete the synthesis of various views, we must first complete the unification of organization and behavior views.

Computer architecture refers to the general term for computer theoretical components and computer basic working principles and theories divided according to different attributes and functions. Among them, the theoretical components of computers are not only linked to an actual hardware, such as the storage part including registers, memory, hard disks, etc.

Computer system structure refers to the organization and interaction between computer hardware and software and the relationship between them. It involves the functions, connection methods, data transmission paths, and the overall design principles and architecture of each component in the computer system.

Computer architecture is the attributes of the computer that programmers see, that is, the logical structure and functional characteristics of the computer, including the interrelationship between its various hardware and soft components.
