I see mentioning JDBC caused people to infer that I equate LINQ with an ORM. Bad analogy on my part perhaps, but I could think of no better way to explain to Java people what LINQ is about. LINQ actually did start out destined for talking to databases, but (thankfully) got factored out into general concepts applicable on any Enumerable[T].
