-This SQLAlchemy model defines a `Book` class that extends the `Base` class. It includes the following columns:
-
-- `id`: A UUID primary key column for the book.
-- `title`: A string column for the book's title, which is non-nullable and indexed for efficient filtering.
-- `author`: A string column for the book's author, which is non-nullable and indexed for efficient filtering.
-- `description`: An optional string column for the book's description.
-
-The model also includes two timestamp columns, `created_at` and `updated_at`, which automatically record the creation and update times for each book record.
-
-Additionally, there is a commented-out section for a potential one-to-many relationship between `Book` and `Author` models. If you need to associate books with authors, you can uncomment this section and create the `Author` model accordingly.
-
-This model should work with FastAPI and Alembic migrations, allowing you to create and manage book records in your database while providing efficient filtering capabilities based on the author and title columns.
