Entity Framework (EF) is an open-source object-relational mapping (ORM) framework used in web development to simplify and automate the access, manipulation, and storage of data in relational databases, such as SQL Server, MySQL, or PostgreSQL, from .NET applications. Entity Framework provides a set of libraries, tools, and APIs that enable developers to work with databases as if they were working with objects, and to perform common tasks, such as querying, filtering, sorting, or updating data, using a high-level, intuitive syntax. Entity Framework supports various data models, such as code-first, model-first, or database-first, and can improve the productivity, flexibility, and maintainability of web applications.
