What is ORM architecture and why is it important?

ORM stands for Object-Relational Mapping. It's a programming technique used to convert data between incompatible type systems in object-oriented programming languages. It allows developers to interact with a database using the same programming language they use for their application, which simplifies database interactions and improves productivity.

Can you explain how ORM works in a practical example?

Sure! Imagine you have a database table for 'Users' with fields like 'id', 'name', and 'email'. With ORM, you can create a 'User' class in your application. When you want to retrieve a user, you can simply create an instance of the 'User' class and use methods to fetch data without writing raw SQL queries.

What are the advantages of using ORM over traditional SQL?

Using ORM can lead to increased productivity, as it reduces the amount of boilerplate code needed for database interactions. It also enhances code readability and maintainability, as developers can work with objects rather than SQL queries. Additionally, ORM frameworks often provide built-in security features to prevent SQL injection.

Are there any downsides to using ORM?

Yes, while ORM can simplify development, it may introduce performance overhead due to abstraction. Complex queries might be less efficient, and developers may need to understand the underlying SQL to optimize performance. Additionally, ORM can sometimes lead to less control over database interactions.
