I'd say - good ol' OO.
class Section {
...
ReadOnlyCollection<Question> Questions ...
void DeleteQuestion(Question q) {
questions.Remove(q);
ReorderQuestions();
}
}
now ReorderQuestions() could be as simple as looping through the questions.
once you hit a perf problem you can switch that into a more efficient SQL
update query. it would be internal to the domain model, not affecting othe
rparts of the application.
