编辑到位与单独的编辑页面/模态？

I have some data that is broken up into sections, much like the Resume feature of StackOverflow Careers (it's not resume data, though), that is editable/create-able via a jQuery web app. It's a bit more hierarchical (jobs can have sub-jobs, etc.) so depending on what method of CRUD I take, it means differing amounts of work. I don't mind spending the time to do it right, but I don't want to spend a lot of time making something fancy that isn't an optimal user experience.I have some data that is broken up into section
