Website:	Go to site
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.
Technology/Standard Usage Requirements:	Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
