Language Integrated Query (LINQ) is a methodology that simplifies and unifies the implementation of any kind of data access.
- provide a solution for the problem of object-relational mapping
- simplify the interaction between objects and data sources
LINQ eventually evolved into a general-purpose language-integrated querying toolset. This toolset can be used to access data coming from in-memory objects (LINQ to Objects), databases (LINQ to SQL), XMLdocuments (LINQ to XML), a file-system, or any other source.
Advantage of LINQ
Developers can use LINQ with any data source.
They can express efficient query behavior in their programming language of choice, optionally transform/shape data query results into whatever format they want, and then easily manipulate the results.
LINQ-enabled languages can provide full type-safety and compile-time checking of query expressions, and development tools can provide full intellisense, debugging, and rich refactoring support when writing LINQ code.LINQ supports a very rich extensibility model that facilitates the creation of ery efficient domain-specific operators for data sources.

Thanks for sharing. But you are mentioned that LINQ introduced for "Technical difficulties encountered when using databases with .NET programming languages"
Can you explain what are those difficulties?
will reply to this..give me a day..
In brief it gives a clear separation from database structure and the business objects that helps the business specific guy (say Business analyst who works with team during requirement gathering phase ) to design overall object without bothering about the database design.
will explain that
