In the internet industry, architecture diagrams serve as an important tool for visualizing the structure 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, and information architecture diagrams.

Module Division: Break down the product into different functional modules, such as user interface, business logic, data storage, payment systems, etc.

Interaction Relationships: Clarify the interaction methods between various modules, such as how users interact with the backend system through the interface, and how different modules exchange data.

Information Flow: Show the flow paths of information between different modules to ensure that each module's functions and data sources are clearly expressed.

Technical Implementation: Include technical aspects such as the technology stack used, database types, server architecture, etc.

Unified User Perception Layer: Addresses the issue of user reach, considering how and in what scenarios users are reached.

Decoupled Business Function Layer: Essentially solves the design issues of the product's core functions, including how to efficiently complete business functions, how to interact with the user layer, and how to communicate data with external systems, among a series of complex business processes.

Centralized Data Processing Layer: Where the product's data comes from, where it is deposited, how the data is efficiently stored, and how it is quickly accessed.

The Product Architecture Diagram is the Parent Level, determining the core modules, platform ends, user roles, etc., serving as the upper-level planning for functional and information architecture diagrams, defining "what is there".

The Functional Architecture Diagram is the Child Level, a detailed result of the product architecture diagram, used to deeply describe the functional items within each module and their hierarchical logic, answering "what can each module do".

The Information Architecture Diagram is the Child Level, focusing on the user's perspective, describing the organization, classification, navigation, and access paths of information, commonly used in UX design and content structure planning, emphasizing "how information is organized and accessed".

1. Clear module functional boundaries
2. Functions are standardized and independent of each other
3. Clear functional boundaries of upstream and downstream products, with clear and reasonable architecture layering
4. Capable of continuous iterative optimization

Before a product officially enters development, drawing a complete product architecture diagram has become essential. The fundamental purpose of a product architecture diagram is to organize product ideas, grasp the overall development direction of the product, and control the key functions of the product. It determines the functions that the product must achieve and when they must be completed.

Additionally, to meet the established product architecture diagram, relevant product development and market operation resources, as well as specific implementation plans, must be equipped, including technology selection and technical paths, market planning, and a series of strategies and measures.
