A bridge is built between domains.
Traditionally, queries against data have been expressed as simple strings without compile-time type checking or IntelliSense support. Additionally, you must
Learn different query languages for various data sources: SQL databases, XML documents, various Web services, and more. LINQ makes queries C# and
First-class language constructs in Visual Basic. You can write queries against collections of strongly typed objects using language keywords and familiar operators. The picture below shows
