Are you aware of ADO.NET? If you are a .NET developer then you would be familiar as you might be using or have used ADO.NET code in your application for data access. For all those who are new to this word, ADO.NET is a set of software components in a computer which is used by the developers to access and modify the data stored in the relational database systems. Although, sometimes writing and managing ADO.NET code becomes a tedious job.

Microsoft has provided an open-source ORM (Object-Relational Mapping) framework for ADO.NET called “Entity Framework” which automates the activities related database. This framework allows the hire entity framework developerto work with relational data using specific domain objects which indeed takes out the need write the data access code. The Entity Framework’s ORM execution supports services like change tracking, identity resolution, lazy loading, and query interpretation so that programmers can concentrate on their business logic for an application rather than data access basics.

Architecture of Entity Framework

Entity Framework is derived from an Entity-Relationship Modeling (ERM) methodology. An ERM outlines a schema of entities and their relationships with each other. Entities are not the same as objects; it only describes the schema of an object, not behavior. Therefore, an entity is something like the structure of a table in the database.

There are mainly three models in Entity framework:

Conceptual Model Storage Model Mapping Model

Benefits of Entity Framework

Productivity Maintainability Performance Simplification of Queries

An excellent thing about Entity Framework is a LINQ Provider. LINQ is used to write the queries in this Framework and it helps the developer to write the effective queries. LINQ is a language backed by .NET compilers that offers a generic SQL-like language.
