What are ORM concepts and why are they 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.
Can you explain how ORM works in a simple way?
Sure! ORM works by creating a mapping between the database tables and the classes in your code. When you want to retrieve or manipulate data, you use the class methods instead of writing SQL queries directly. The ORM handles the conversion between the two.
What are some popular ORM frameworks?
Some popular ORM frameworks include Hibernate for Java, Entity Framework for .NET, and Sequelize for Node.js. Each of these frameworks provides tools to simplify database interactions.
Are there any downsides to using ORM?
Yes, while ORM can simplify database interactions, it can also introduce performance overhead and may not support complex queries as efficiently as raw SQL. It's important to evaluate when to use ORM based on your project's needs.
