How can you structure a unified data schema for the entire project?

To structure a unified data schema in a project, you can use a centralized data model description that serves as a single source of truth for all components.

Approaches:

• Using ORM (e.g., SQLAlchemy, Django ORM) with model definitions in one place.
• Using schemas in JSON Schema or YAML format to describe data structure.
• Creating a separate module or package with class or structure definitions that are imported across the project.

Example with Pydantic in Python for a unified schema:

from pydantic import BaseModel

class User(BaseModel):
    id: int
    name: str
    email: str

# Used in different modules for validation and serialization

This approach ensures consistency and simplifies data maintenance in the project.
