To me the important thing that turned the lights on regarding relational databases, is to think in terms of sets. If you are thinking in terms of rows and columns you tend to fall into iterative, imperative patterns. Think in terms of sets and frame your thinking about queries in declarative terms of sets, intersections, unions, filters, etc.
