What are the differences between ORM and validation in software development?

ORM, or Object-Relational Mapping, is a technique that allows developers to interact with a database using object-oriented programming. Validation, on the other hand, is the process of ensuring that the data meets certain criteria before it is processed or stored.

Can you give me examples of how ORM is used?

Sure! In a web application, ORM can be used to map database tables to classes in your code. For instance, if you have a 'User' table, you can create a 'User' class that represents that table, allowing you to easily create, read, update, and delete user records without writing raw SQL.

And what about validation? How is it implemented?

Validation can be implemented using various methods, such as using built-in validation libraries or writing custom validation logic. For example, in a form submission, you might validate that an email address is in the correct format and that required fields are not empty before processing the data.

Are there any frameworks that combine both ORM and validation?

Yes, many frameworks like Django and Ruby on Rails provide built-in support for both ORM and validation, making it easier for developers to manage data integrity and database interactions.
