In LINQ to Entities, what is an Entity Data Model (EDM)?

  • A method for executing SQL queries directly on the database
  • A programming language for querying databases
  • A representation of the conceptual model of data in a database
  • A tool for designing user interfaces
An Entity Data Model (EDM) in LINQ to Entities represents the conceptual model of data in a database. It defines the structure of the data and the relationships between entities. EDM provides a higher-level abstraction over the database schema, allowing developers to work with entities and relationships rather than tables and columns directly.
