Overview of LINQ To SQL

In LINQ to SQL, the data model of a relational database is mapped to an object model expressed in the programming language used by the developer. When the application runs, LINQ to SQL converts the language integration queries in the object model into SQL, and then sends them to the database for execution. When the database returns results, LINQ to SQL converts them back to objects that you can process in your own programming language.

LINQ To SQL object model

In LINQ to SQL, the object model represented by the developer's programming language is mapped to the data model of the relational database. The operation on the data is then performed according to the object model.

In this case, instead of issuing database commands to the database (for example, INSERT), you change the values and execute methods in the object model. When you need to query the database or send changes to it, LINQ to SQL converts your request into the correct SQL commands, and then sends those commands to the database.
