What is LINQ in C# ?

[Stencel]

Basically LINQ address the current database development model in the context of Object Oriented Programming Model. If some one wants to develop database application on .Net platform the very simple approach he uses ADO.Net. ADO.Net is serving as middle ware in application and provides complete object oriented wrapper around the database SQL. Developing application in C# and VB.Net so developer must have good knowledge of object oriented concept as well as SQL, so it means developer must be familiar with both technologies to develop an application. If here I can say SQL statements are become part of the C# and VB.Net code so it’s not mistaken in form of LINQ.

I think this comment gives a pretty good guideline about deciding between deferred vs not. Apart from that it seems we have to think about what the function is doing and whether it needs entire set of data to fulfill it's function

Still lots of folks don’t understand what LINQ is doing. Basically LINQ address the current database development model in the context of Object Oriented Programming Model. It has a single unitive syntax for querying multiple data sources such as relational data and XML data.
