It boils down to two things: code and data. Writing software is not so simple, and one of the major activities it involves is programming code to deal with data. To write code, we can choose from a variety of programming languages. -

The LINQ Project .NET Language Integrated Query May 2006
The LINQ Project .NET Language Integrated Query May 2006 Don Box, Architect, Microsoft Corporation and Anders Hejlsberg, Technical Fellow, Microsoft Corporation Copyright © Microsoft Corporation 2006. All Rights Reserved. .NET Language Integrated Query .NET Language Integrated Query After two decades, the industry has reached a stable point in the evolution of object oriented programming technologies. Programmers now take for granted features like classes, objects, and methods. In looking at the current and next generation of technologies, it has become apparent that the next big challenge in programming technology is to reduce the complexity of accessing and integrating information that is not natively defined using OO technology. The two most common sources of non-OO information are relational databases and XML. Rather than add relational or XML-specific features to our programming languages and runtime, with the LINQ project we have taken a more general approach and are adding general purpose query facilities to the .NET Framework that apply to all sources of information, not just relational or XML data. This facility is called .NET Language Integrated Query (LINQ). We use the term language integrated query to indicate that query is an integrated feature of the developer’s primary programming languages (e.g., C#, Visual Basic). Language integrated query allows query expressions to benefit from the rich metadata, compile- time syntax checking, static typing and IntelliSense that was previously available only to imperative code. Language integrated query also allows a single general purpose declarative query facility to be applied to all in-memory information, not just information from external sources. .NET Language Integrated Query defines a set of general purpose standard query operators that allow traversal, filter, and projection operations to be expressed in a direct yet declarative way in any .NET-based programming language. -
