ORM Validation

ORM Validation is a technique in software development where data integrity and business logic rules are enforced within an Object-Relational Mapping (ORM) layer, typically through declarative constraints or custom validation logic. It ensures that data objects (models) adhere to specified rules before being persisted to a database, such as checking for required fields, data types, or custom conditions. This approach centralizes validation logic, reducing redundancy and improving maintainability in applications that use ORMs.

Also known as: ORM Data Validation, Model Validation, Object Validation, Database Validation via ORM, ORM Constraint Validation

Why learn ORM Validation?

Developers should use ORM Validation to enforce data consistency and prevent invalid data from entering the database, which is crucial for applications with complex business rules or high data integrity requirements, such as e-commerce platforms or financial systems. It simplifies development by integrating validation directly into the ORM, reducing boilerplate code and errors compared to manual validation in controllers or services, and is particularly useful in web frameworks like Django, Laravel, or Ruby on Rails that rely heavily on ORMs.
