Async SQLModel CRUD operations use AsyncSession to execute create, read, update, and delete queries with safe transaction handling. You configure table=True models and manage sessions asynchronously to build scalable data layers.

SQLModel relationships use back_populates for bidirectional mapping between models. You configure foreign keys and use joins or subqueries to efficiently fetch related data across entities like Students and Classes.

The best way to add pagination and filtering to SQLModel queries is constructing complex query statements with offset, limit, and conditional filters. This enables efficient data retrieval and ordering across related database entities.

SQLModel fully supports Pydantic validators and database constraints. You can define indexed fields, unique constraints, and field validations directly within your table=True models to enforce data integrity at the database and application levels.

SQLModel database models enforce created_at and updated_at timestamps by defining datetime fields with automatic population. This tracks record lifecycle events automatically across your CRUD operations and data layer.
