- Comparing non-nullable columns is simpler and faster than comparing nullable columns. Consider marking columns as non-nullable whenever possible.

- Checking for equality (`==`) is simpler and faster than checking for non-equality (`!=`), because query doesn't need to distinguish between `null` and `false` result. Use equality comparison whenever possible.However, simply negating `==` comparison is effectively the same as `!=`, so it doesn't result in performance improvement.
