ORM

May 1, 2024 Updated July 1, 2025 11 minute read

Object-relational mapping (ORM) is a programming technique that allows programmers to create objects that correspond to the data in a relational database. This makes it easier to work with data in a database, as programmers can use the objects to represent the data instead of having to write SQL queries directly. ORM frameworks take care of the plumbing involved in mapping objects to database tables, allowing developers to focus on writing business logic and less on data access code.
