+# Back-end Flask Project
+
+## Overview
+This project is a basic Flask application structure designed to demonstrate the organization of a Flask project. It includes essential components such as routes, models, templates, and configuration files.
+
+## Project Structure
+```
+Back
+├── app
+│   ├── __init__.py
+│   ├── routes.py
+│   ├── models.py
+│   └── templates
+│       ├── base.html
+│       └── index.html
+├── tests
+│   └── test_app.py
+├── app.py
+├── config.py
+├── requirements.txt
+└── README.md
+```
+
+## Setup Instructions
+
+1. **Clone the repository**:
+   ```
+   git clone <repository-url>
+   cd Back
+   ```
+
+2. **Create a virtual environment**:
+   ```
+   python -m venv venv
+   ```
+
+3. **Activate the virtual environment**:
+   - On Windows:
+     ```
+     venv\Scripts\activate
+     ```
+   - On macOS/Linux:
+     ```
+     source venv/bin/activate
+     ```
+
+4. **Install dependencies**:
+   ```
+   pip install -r requirements.txt
+   ```
+
+5. **Run the application**:
+   ```
+   python app.py
+   ```
+
+## Usage
+Once the application is running, you can access it at `http://127.0.0.1:5000/`. The index page will be displayed.
+
+## Testing
+To run the tests, ensure the virtual environment is activated and execute:
+```
+pytest tests/test_app.py
+```
+
+## Contributing
+Feel free to submit issues or pull requests for improvements or bug fixes.

+数据库设计说明：
+1.	核心表结构：
+	users：存储用户信息，包含角色管理和账号状态
+	posts：核心内容表，支持多模态内容（图文/视频/文档）
+	behaviors：记录用户互动行为（点赞/收藏/浏览等）
+	comments：评论系统，支持多级回复
+	follows：用户社交关系
+2.	推荐系统支持：
+	posts.heat 字段存储动态计算的热度值
+	behaviors 表记录用户行为用于协同过滤
+	user_tags 表构建用户兴趣画像
+	通过 post_tags 实现内容标签分类
+3.	多模态内容处理：
+	posts.media_urls 使用 JSON 类型存储多个资源 URL
+	posts.type 区分不同类型的内容（图文/视频/文档）
+4.	审核与安全：
+	audits 表记录内容审核历史
+	posts.status 管理内容生命周期状态
+	logs 表记录系统操作和访问日志
+5.	性能优化：
+	为查询频繁字段添加索引（热度/行为类型/时间）
+	使用 JSON 类型存储灵活数据（通知内容/媒体资源）
+	通过 heat 字段预计算支持热门排序
+6.	扩展性设计：
+	用户画像系统通过 user_tags 表实现
+	通知系统支持多种互动类型
+	行为表设计支持未来扩展新行为类型

+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
