LINQ to SQL provides a run-time infrastructure for managing relational data as objects. Relational data appears as a collection of two-dimensional tables, where common columns relate tables to each other. In LINQ to SQL, the data model of a relational database is mapped to an object model expressed in Visual Basic.
This video shows you how to create a basic LINQ to SQL application. The following tasks are included in the process:
Mapping a class to a database table.
Designating properties on the class to represent database columns.
Specifying the connection to the database.
Creating a simple LINQ query to run against the database.
Executing the query and observing the results.
The Visual Basic Help includes the code and the steps that are demonstrated in this video. See Walkthrough: Simple Object Model and Query (Visual Basic) (LINQ to SQL).
