Object Relational Mapping

Object Relational Mapping (ORM) is a programming technique that facilitates the interaction between object-oriented programming languages and relational databases. It acts as an abstraction layer, allowing developers to manipulate database entities using objects and classes instead of writing SQL queries directly. This can significantly simplify data management and enhance productivity, especially in web application development.

ORMs enable developers to create, read, update, and delete data using the programming language they are comfortable with, such as Python. For instance, instead of writing SQL statements, a developer can use ORM methods to perform database operations. Popular ORM libraries in Python include SQLAlchemy and Peewee, each offering unique features and capabilities 124.

Using an ORM can also make it easier to switch between different relational databases, as the ORM handles the underlying database interactions, allowing for greater flexibility in development 24.

If you have more specific questions about ORM or its applications, feel free to ask!
