In the internet industry, architecture diagrams are an important tool used to visually display the architecture of software, systems, applications, and the relationships between their components. Common types of architecture diagrams include: business architecture diagrams, application architecture diagrams, system architecture diagrams, technical architecture diagrams, deployment architecture diagrams, data architecture diagrams, product architecture diagrams, functional architecture diagrams, information architecture diagrams, etc.

Correspondence: Product goals correspond to user needs.

Similarity of functions: By classifying, similar functions are grouped together. The main framework of the product is based on large categories, while small categories serve as sub-frameworks to form the entire product framework.

Relationship between functions: Containment relationship--there is an upstream and downstream dependency relationship between functions, which can be a vertical information architecture; Parallel relationship--there is no association between two functions, so a horizontal information architecture can be considered.

Frequency of function usage: The higher the frequency of use, the more important the function is, and it should be placed in the most accessible place, with priority given to designing the architecture around core functions.

System scalability: As the product evolves from 0 to 1, and from 1 to N, product functions are continuously added and improved. This requires preparing for expansion when designing the information architecture and considering future scalability.

The focus of the information architecture diagram is to organize specific pages and their field information. When it comes to the interface, the relationships between pages need to be clearly presented. This stage also lays the foundation for drawing prototypes and information layout. Interaction designers need to draw the information architecture diagram in advance before outputting the interaction draft.

Hierarchical structure: Also known as a tree structure or central radiation structure, in a hierarchical structure, nodes have a parent-child relationship with other related nodes. Each node has a parent node but may not have child nodes. The top-level parent node is called the root node.

Matrix structure: The matrix structure allows users to move between nodes along two or more dimensions, ultimately helping users find the information they want.

Natural structure: The natural structure does not follow any consistent pattern. Nodes are connected one by one, and there are connections between nodes, but no classification.

Linear structure: In a linear structure, users cannot jump; they can only browse the corresponding information step by step in order.

Top-down: The top-down construction method is driven by the strategic layer, directly designing the structure based on product goals and user needs, used for new product planning or product redefinition.

Bottom-up: The bottom-up construction method is driven by the scope layer, designing based on the analysis of existing content and functional needs. This is the most commonly used method in project practice.

Comprehensive application: Both top-down and bottom-up construction methods have obvious shortcomings, so the ideal way to build information architecture is to use a comprehensive application, driven by both the strategic and scope layers, to build a highly adaptive system.

Website design: Show the organization of website content, helping users and designers understand the website structure.

Software and databases: Organize and display software functional modules or database records to improve usability and findability.

Information systems: Plan and design the navigation structure and information flow of large information systems.
