Here is an updated diagram that shows how the project is conceptually organized:

Each vertical box is a use case (or slice), while each horizontal arrow is a crosscutting concern or some shared components. This is a small project, so the data access code (DbContext) and the Product model are shared between all use cases.

Here are the actors:

• ProductsController is the web API entry point to manage products.
• StocksController is the web API entry point to manage inventory (add or remove stocks).
• AddStocks, RemoveStocks, and ListAllProducts...
