How do ORMs compare to query builders in terms of performance?

ORMs (Object-Relational Mappers) abstract database interactions, while query builders provide more control over SQL. Generally, query builders can be faster because they allow for optimized SQL queries, but ORMs can speed up development time.

What are some specific scenarios where one might be better than the other?

If you're working on a small project with simple queries, an ORM can save time. However, for complex queries or performance-critical applications, a query builder might be more efficient.

Can you give examples of popular ORMs and query builders?

Sure! Popular ORMs include Hibernate for Java, Entity Framework for .NET, and Sequelize for Node.js. For query builders, you might look at Knex.js for JavaScript or SQLAlchemy for Python.

Are there any benchmarks available for comparing their performance?

Yes, there are several benchmarks available online that compare the performance of ORMs and query builders. They typically measure query execution time, memory usage, and ease of use.
