Description: Microsoft Entity Framework (EF) is an open-source Object-Relational Mapping (ORM) framework that enables .NET developers to work with a database using .NET objects. EF uses a provider model that allows EF to map with and access many databases, which enables developers to work with data in the form of domain-specific objects and properties and create and maintain data-oriented applications with less code than in traditional applications.

All EF applications have two major layers: a modeling layer and an object layer. EF uses the modeling layer to transform operations against entity objects, such as create, read, update, and delete, into equivalent operations in a connected database.

EF supports Microsoft Structured Query Language (SQL) Server, DB2, MySQL, Oracle Database, Maria Database (MariaDB) and PostgreSQL.

This entry covers both Entity Framework and Entity Framework Core.
