Watch this: LINQ shifts the paradigm of query LINQ = .Net language-integrated query.

The article discusses how the use of language-integrated query (LINQ) affects information search queries. The author illustrates the use of structured query language (SQL) in searching for information from information stores comprised of XML documents. He suggests searches using LINQ do not need to divide searches between databases and XML documents due to information storage architecture. He notes the creation of database systems, such as the DB2 Universal Database, that incorporate both XML and SQL data storage structures and discusses the introduction of LINQ at the Professional Developer's Conference by programmer Anders Hejlsberg.
