这种结构分离了关注点，使得随着项目规模的扩大而更容易管理。

关键目录和文件：
- app/main.py：fastapi 应用程序的入口点。它启动应用程序，包括路由器和其他配置。
- api/：包含库存系统各个方面（产品、库存、销售、用户）的路由定义。
- db/：包括 sqlalchemy 模型、数据库会话设置和相关文件。
- crud/：通过crud操作处理数据库和api之间的交互。
- schemas/：定义用于验证和序列化请求和响应数据的 pydantic 模型。
- services/：包含系统各种功能的业务逻辑。
- tests/：包含单元测试和集成测试以确保功能。
- alembic/：如果您使用 alembic 进行数据库迁移，这就是迁移文件所在的位置。
这种结构对于库存系统来说是灵活且可扩展的，促进关注点分离，更容易测试和维护。
