Architectural design refers to the process of overall planning the structure, components, and interaction of the system when building a complex system. It focuses on the interrelationships between components in a system and how the system is divided into modules and layers. Proper application architecture design not only helps improve system performance and stability, but also provides users with a better user experience.
Architectural design refers to the overall planning and design of the system to meet specific needs and functions during the development process of software or computer systems. It focuses on the interrelationship and interaction between the various components in the system, and how to divide the system into different modules and levels. Architectural design aims to reduce the complexity of the system and improve the understandability and maintainability of the system.
When designing an architecture, there are some important principles to follow:
Modularization: Divide the system into multiple modules, each module is responsible for specific functions, thereby reducing the complexity of the system and facilitating teamwork and maintenance. Loose coupling: Dependencies between modules should be minimized so that specific functions can be modified and replaced without affecting the functions of other modules. High cohesion: Each module should focus only on its own functions as much as possible and maintain high cohesion for easy understanding and maintenance. Abstraction: Through abstraction, complex details are hidden, making the system design simpler and easier to understand. Scalability: The future expansion needs of the system should be taken into consideration when designing to ensure that the system can easily add new functions or adapt to application scenarios of different sizes.The main goal of architectural design is to create a system that meets user needs and has good quality attributes. The following are some of the main goals of architectural design:
Functionality: The architecture of the system must meet the functional needs of users and ensure that the system can complete established tasks. Performance: The system should have efficient performance, including response speed, throughput and resource utilization. Reliability: The system should have high reliability, that is, it should be able to continue to operate normally in the face of failures or abnormal situations and be able to recover in a timely manner. Maintainability: The system should be architected to be easy to maintain and debug, allowing the development team to quickly identify and fix problems. Scalability: The architecture design should take into account future expansion needs so that the system can easily add new functions or adapt to changing needs. Security: The system architecture needs to take into account security requirements to ensure that the system is not protected from malicious attacks and data leaks.Architectural design is a core concept in computer science and software engineering, which involves the planning and design of the overall system. By following a set of principles, architectural design helps build systems that are performant, reliable, maintainable, and scalable. In fields such as software development, network architecture, enterprise architecture, embedded systems, and cloud computing, reasonable application architecture design can provide better user experience and technical support for various applications.
Extended reading: What are the architectural design methods?
There are many architectural design methods, each of which can be chosen based on different projects and needs. Here is a brief introduction to several common architecture design methods:
1. Object-Oriented Design
Object-oriented design is a common architectural design method that decomposes a system into multiple objects, each with its own properties and methods, and interacts through message passing. This method emphasizes encapsulation, inheritance and polymorphism, which can improve code reusability and maintainability.
2. Service-Oriented Architecture (SOA)
SOA is a service-based architecture design method that splits the system into multiple autonomous service units that communicate through standardized interfaces. SOA can improve the flexibility and scalability of the system, making the system easier to integrate and reuse.
3. Domain-Driven Design (DDD)
DDD is an architecture design method that combines software system modeling with domain knowledge. It divides the system into multiple domains and describes and solves problems through domain models. DDD emphasizes clear domain models and business logic, helping the development team better understand and implement business requirements.
4. Layered Architecture
Layered architecture is an architectural design method that divides the system into multiple logical levels. Each layer is responsible for a specific function and only interacts with adjacent layers. This approach helps reduce system coupling and improve maintainability and scalability.
5. Event-Driven Architecture (EDA)
EDA is an architectural design method based on events and messages. Various components in the system communicate through asynchronous events, enabling decoupling and highly flexible system architecture.
6. Microservices Architecture
Microservice architecture is an architectural design method that splits the system into small, independent service units. Each service unit can be developed, deployed and run independently, helping to achieve agile development and deployment.
7. Service-Oriented Design
Service-oriented architecture is an architectural design method that divides system functions into services. Each service provides specific functionality and interacts with other services through interfaces.
8. Event Storming Method
Event storming is an architectural design method based on teamwork. Team members use an immersive approach to gradually demonstrate business processes and events to help understand and discover system requirements.
The above introduces some common architectural design methods, each method has its applicable scenarios and advantages. In practical applications, architectural designers need to select appropriate methods based on the characteristics and needs of specific projects, and implement them based on the team's technology and experience. Good architectural design can help ensure system stability, performance, and maintainability, thereby meeting user needs and promoting successful project implementation.
