In real product development, what can be written in the back-end design specifications?
Back-end design specifications for product development typically include the following:
Data model design: Describe the structure of the database in detail, including the design of data tables, field definitions, and relationship settings.
Business logic design: Describe the back-end business logic in detail, including the design of various algorithms, control of business processes, etc.
API design: Define various service interfaces provided by the backend, including the URL of the interface, request method, request parameters, response results, etc.
Performance optimization design: How to deal with high concurrency, latency and capacity issues, including caching strategies, load balancing, database optimization, etc.
Security design: How to prevent security issues such as XSS, CSRF, SQL injection, etc., including input filtering, verification code design, session management, etc.
Error handling design: Describe in detail various possible error conditions and corresponding handling methods.
Architecture design: including the overall architecture of the system, module division, service splitting, etc.
Code specifications: In order to ensure the readability and maintainability of the code, some code writing specifications need to be formulated.
Testing strategy: including unit testing, integration testing, stress testing, etc.
Deployment planning: including server configuration, network settings, software installation, etc.
Version control: used to manage code versions, including version library selection, branch management, merge strategies, etc.
Each company or project may need to adjust the content of the design specification based on its own actual circumstances. But in general, the design specification should be as detailed and comprehensive as possible so that team members have a clear understanding of the back-end design.
