 Use Buffalo pop `Soda CLI` to create database migrations.

 Implement the architecture design for User entity.
 
 Checked out OpenAPI, and found that it was not that simple at all. It needs
 a whole package of knowledge about the web development!
-
-For the test-driven part,
-
-- model layer: just model designs, **nothing to test**
-- infra: routes and db connections, it works when it works. Nothing to test.
-- registry: Just return some structs, no logic. **Not worth testing**
-- adapter:
-    - input-port (controller) test: it is about testing parsing the input
-    value, and the output results writing. The unit test of controller is to
-    **make sure that they behave as defined in the API documentation**. To
-    test, we have to mock the **business service**.
-    - output-port (repo) test: it is about testing converting business model
-    to database model and the interaction with the database. If we are going
-    to test them, it's about simulating different type of database behaviour
-    (success, timeout, etc.). To test, we have to mock the
-    **database connection**.
-- usecase: This is the core part to test, it's about the core business.
-We provide the data input and we check the data output in a fake repository.
-
-With this design, although it may seem overkill for this little project, fits
-perfectly well with the TDD method.
-
-Concretely, I will do the TDD for my usecase level development, and for the
-rest, I just put unit tests aside for later.
-
-#### Workflow
-
-1. OAS Definition
-2. (Integration/Validation test)
-3. Usecase unit test cases
-4. Usecase development
-5. Refactor (2-3-4)
-6. Input-port/Output-port
-
-That should be the correct workflow. But to save time, I will cut off the
-integration test part (the 2nd point).
