What are the common system architectures?

1. Monolithic kernel, also known as macro kernel. The single-kernel structure is an operating system.The form of mixed kernel components in China. This structure is the longest in the 1960s (and some are said to be in the early 1950s, which is still controversial). It is the original form when the operating system kernel was separated from the periphery.

2. Load Balance Cluster Load Balancing System: All nodes in the cluster are active, and they share the workload of the system. Generally, Web server clusters, database clusters and application server clusters all belong to this type.

3. Generally speaking, personal computers are divided into two types in terms of system architecture: microprocessor architecture (x86 architecture): personal computers with this architecture usually use Intel or AMD microprocessors, such as Intel Core or AMD Ryzen Wait.

4. ARM architecture ARM architecture is a streamlined instruction set computer (RISC) architecture designed by the British company ARMHoldings. ARM architecture was first applied to the field of embedded systems, such as mobile devices, smart watches, etc. At present, ARM architecture is also widely used in servers, supercomputers and other fields.

5. Hierarchy of computer system: microprogram design level --- level 1 The programming tool of this level is a micro-instruction set. The microprogram written by programmers with micro-instructions is directly executed by the hardware.

System Overall Architecture

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

2. The data in the business architecture, including internal data, external system data and user behavior data, together form a closed loop of data flow. Application architecture comes from the business organization and describes the functional modules in a system. When writing an application architecture diagram, it is often necessary to describe the entire platform architecture from the perspective of the whole platform.

3. The overall structure of the accounting information system is composed of three modules: data module, operation module and information module. 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.

How to describe the norms and standards in the information system architecture?

The use of standards can also be used to improve the manageability of the system, thus reducing the cost of ownership of information systems. Therefore, enterprise informatization standards are to combine the technical and business standards of the industry at the level of enterprise-level architecture to form standards suitable for the enterprise itself, rather than a simple accumulation of technical and business standards.

The task in the system analysis stage is based onThe scope determined by the system development plan conducts a detailed investigation of the current system, describes the business process of the current system, points out the limitations and shortcomings of the current system, and determines the basic goals and logical model of the new system. This stage is also known as the logical design stage.

Informationsystem is a human-machine integrated system composed of computer hardware, network and communication equipment, computer software, information resources, information users and rules and regulations for the purpose of processing information flow. There are five basic functions, namely input, storage, processing, output and control of information.

Information technology architecture is a comprehensive structure that adopts and develops information technology to achieve strategic goals. It includes the components of management and technology. Its management components include mission, function and information requirements, system configuration and information process;Technical components include information technology standards, rules, etc. used to realize the management architecture.

The operation process of an enterprise must first have a general business flow chart to describe the relationship between various businesses in the enterprise, and then describe each business in detail to combine business processes with departmental responsibilities. The detailed business flow chart can be in the form of a straight business flow chart.

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? Object-oriented programThe concepts in sequential design mainly include: objects, classes, data abstraction, inheritance, dynamic binding, data encapsulation, polymorphism, and message passing. 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.

4. The functional architecture of the MEC system mainly includes the following parts: MEC server: the core component of the MEC system, providing network slicing, edge computing, network acceleration, security isolation and other functions. Business control layer: responsible for controlling and managing MEC servers to realize business scheduling, resource allocation, security policy and other functions.

5. Simply put, system architecture design is a sketch of a system that describes the abstract components that make up the system and how each component communicates. These components can be refined into actual components such as classes or objects during the implementation process.

What is system architecture

Software architecture refers to the overall organizational structure of the software, which is analyzed and designed at a higher level, reflecting the overall regulation, decision-making, control, etc. of the software system. The system architecture includes software, hardware, network and other aspects of organizational structure. Architecture is the high-level stage of analysis and design. It will not involve the details of technical realization. It is a blueprint, regulation and decision-making.

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

System architecture: System architecture is to frame the technical implementation of the identified needs, make a good plan, use a complete set of tools, and complete the task in the planning steps. Technical framework: The technical framework is a reusable design framework for the whole or part of the technical system.

System architecture is to frame and make a good plan for the technical implementation of the identified needs, and use a complete set of tools to complete the task in the planning steps. Technical structure Evaluate, analyze and improve the constituent frameworks and models of organizations, networks and programs through reasonable and perfect evaluation channels.

whatWhat is the composition of the computer? Computer architecture (puterArchitecture) is the attributes of the computer that programmers see, that is, the conceptual structure and functional characteristics. According to the multi-level hierarchy of the computer system, the computers seen by different levels of programmers have different attributes.

system software architecture

1, III) microkernel architecture microkernel architecture is also known as plug-in architecture E), refers to the relatively small kernel of the software, and the main functions and business logic are implemented through plug-ins. The core usually contains only the minimum functions of the system operation.

2. Software architecture is a series of related abstract patterns used to guide the design of various aspects of large-scale software systems. Software architecture is a sketch of a system. The objects described by the software architecture are the abstract components that directly constitute the system. The connection between components clearly and describes the communication between components in a clear and relatively detailed way.

3. According to the different perspectives we focus on, the architecture can be divided into three types: the relationship between components in the software system, such as user interface, database, external system interface, business logic components, etc.
