As software developers, we spend a lot of time extracting and displaying data from many different data sources. Whether it's a XML webservice of some sort, or a full featured relational database, we have been forced to learn different methods of data access. Wouldn't it be great if the method of access was the same for all data sources? Well, we are in luck because, as of the release of C# 3.0 and the .NET 3.5 Framework, LINQ has come to change the game forever.

Current Data Access Overview

On the .NET platform we have been and still are utilizing ADO.NET for accessing different data sources. The open source community has also provided the developers with a number of alternatives.

Language Integrated Query is the new addition to the .NET family and as the name suggests it's the kind of query style data access which is fully supported by the language to effectively unify the way we access data and to make our lives easier. LINQ is able to target a number of different sources namely Oracle, MSSQL, XML and a few others, but for now we will focus on the most basic of all, LINQ to Objects.
