Object Relational Mapping

Object Relational Mapping (ORM) is a programming technique that facilitates the interaction between object-oriented programming languages and relational databases. By providing a high-level abstraction, ORMs allow developers to manipulate database records as if they were regular objects in their code, eliminating the need for complex SQL queries. This approach streamlines data handling, making it easier to create, read, update, and delete records. However, while ORMs can enhance productivity and simplify database interactions, they may also introduce challenges such as performance issues and increased complexity in certain scenarios. Understanding the balance between using ORMs and direct SQL is essential for effective database management.
