The video tutorial introduces Object Relational Mappers (ORMs), explaining their role in programming as tools that allow developers to interact with databases using programming languages instead of specific query languages like SQL. It provides an example using JavaScript and the Sequelize library, highlighting how ORMs make database interactions more human-readable and organized. The tutorial compares ORM usage with raw SQL queries, discussing the benefits of ORMs, such as time-saving and code organization, alongside drawbacks like learning curve and potential performance issues. The video concludes with a recap of ORM's advantages in simplifying database queries.
