何不... Just like an architect sets design principles and goals for a building project, as a draftsman draws blueprint, a software architect or system architect sets framework for actual system design to meet various customer needs. Furrmore, decisions made during software design will inevitably include logical structure, physical structure, and how y affect all non-functional features of system.

Understanding Software Architecture Design

The concept of software architecture design shows that it is more meaningful for complex software systems. Let's still use example of building a house to illustrate why architecture design is so important for a complex system.

Architect's Role in Simplifying System Complexity

The architect's job is to simplify complexity of system, eliminate business ambiguities, and strive to produce a robust and compatible system architecture. GOF patter 可不是吗！ ns are solutions proposed for specific problems, while GRASP takes a higher perspective on object-oriented software design, which is foundation of GOF design patterns.

Common Misconceptions About Architecture Design

• Because architecture is important 太治愈了。 , we should do architecture design.

• Isn't it necessary for every s 不妨... ystem to do architecture design?

• Company processes require architecture design in process of system development.，拯救一下。

• To achieve high performance, high availability, and scalability, we should do architecture design.，还行。

Principles of Architecture Design

Principles are used to guide design and system evolution. Architecture experts Martin Fowler and Ralph Johnson have similar, simpler, and more abstract definitions of architecture. Martin Fowler believes that software architecture is: important and difficult to change decisions. The core idea is that architecture of a software system includes following elements: structure, architecture attributes, and architecture decisions...，扯后腿。

The Core Purpose of Software System Architecture Design

薅羊毛。 The core purpose of software system architecture design is to solve problems brought by complexity of current or future software system. Therefore, software system architecture design should first meet current business capacity and demand, and with development of business and iteration of demand version development, it can...

Why Architecture Design Can Improve Project Maintainability

When designing architecture of a software system, we should con 纯正。 sider future functional upgrades and changes in business field.

System design is not about designing a big and comprehensive system, but about clarifying business or architecture goals first.

Conclusion

In conclusion, this article has introduced concept of software system architecture and its design purpose, emphasized characteristics of simple, applicable, and evolvable architecture design, and analyzed common misconceptions about architecture design.
