Entity Framework is an Object-Relational Mapping (ORM) framework that is used to interact with databases in .NET applications. It is a part of the .NET ecosystem and is developed by Microsoft. Entity Framework provides a high-level abstraction over the database, allowing developers to work with data in terms of objects and classes instead of writing raw SQL statements.
Entity Framework supports a range of database systems, including Microsoft SQL Server, Oracle, MySQL, and PostgreSQL, and provides several features to make working with databases easier, including:
Entity Data Model: a conceptual model that describes the structure of the data, and how it is related.
LINQ-to-Entities: a language-integrated query that allows developers to write queries in C# or VB.NET instead of using SQL.
Change Tracking: Entity Framework can track changes made to objects and persist those changes to the database.
Lazy Loading: Entity Framework can automatically load related objects on demand, which can improve performance and reduce the amount of code that developers need to write.
Overall, Entity Framework is a powerful and flexible tool that can simplify data access in .NET applications, and is widely used in enterprise software development.
Entity Framework is an object-relational mapping (ORM) framework for .NET applications developed by Microsoft. It provides an abstraction layer that allows developers to work with databases using objects instead of writing traditional SQL queries.
Using Entity Framework, developers can define a conceptual model for their application that maps to the underlying database schema. They can then use LINQ (Language-Integrated Query) to query and manipulate data, with the framework automatically generating the necessary SQL statements to execute those queries.
Entity Framework also supports a range of features, including code-first development, lazy loading, and automatic change tracking. It can be used with a variety of databases, including SQL Server, Oracle, MySQL, and PostgreSQL.
Overall, Entity Framework simplifies the process of working with databases in .NET applications and can help developers write more efficient, maintainable code.
