LINQ to SQL ends up creating an expression on IQueryable. You can build this expression up any way you want, including in bits and pieces. You can tack on Wheres and Selects any time you like. It's more composable than pain text SQL since the parts can go in any order. It's only after you force it to materialize (I.e. call ToList) that you can't further "compose" it.
