NextnPrevious pages and database update

Question

Hi Folks,
Am hoping someone can point me in the right direction on figuring this out...
I have 120 individuals in the database with related fields. Instead of displaying 120 rows when I pull the data from the database, I've built Next/Previous pages for displaying them 30 to a page.
Here's the thing: This is an admin section, pulling names and IDs and fields (text, radio buttons, dropdowns, etc.) for data entry, or rather, database update.
So, after displaying 30 on the page you have a link on the bottom of the page to display the next 30. This page refreshes itself...
Either I have to cache the update info from each page and put a submit button for updating on the last page or, submit each page (30 at a time) until each succeeding page is done, one at a time. See what I'm getting at? I think I'd rather be able to submit 30 at a time instead of trying to cache all the data as you move from page to page but am having a hard time trying to figure this out.
I'm not sure what is best or just how to do the database insert/update since the Next/Previous CF code depends on the same page refreshing itself each time for the next pages.
Also, the first page of this 'group of NextPrevious pages' is dependant on it's previous page of "select school", so that the first NextPrevious page (and following ones) displays the individuals from that particular school - 30 at a time.
Can anyone point me in the right direction on this kind of database insert/update when used in conjunction with Next/Previous page links?
Thanks!

Thank ya'll for the ideas...
You know, before posting this I googled and googled and was surprised to find hardly anything addressing this. I would have thought it would be a fairly common way to perform edits on a large number of table rows - when you only want to display, say, 30 per page instead of 1200 records on one web page for admin edits.
With Meensi's and Furnis' suggestions and, a bit more thought... I kept thinking... It's pretty much like a shopping cart - holding a variable(s) from page to page. I know there's many ways to do this but the problem here lies in the page refresh holding variables with each refresh.
Seems logical to update All edits at one time - submit the form on the last page. I'm wondering, say as in the case you may have 1200 NextPrevious pages (!) - You'd want the user to do it in bits, page per page.
Since a clicked link clears session variables... maybe make the page refresh link (Next Page) a submit button and, on refresh, submit just "this particular page variables" and at the same time, the refresh loads the Next Page variables - updating the database in increments and display the next batch to edit.(?)
Does this make sense? I do want to make this a 'no-brainer' for the user - an admin section being most intuative is foremost to me...
The following is (stripped down) code I'm using to run the NextPrevious pages. I think maybe if I add the database insert somewhere in the code at the top of the page, coming from a form submit button that refreshes the page at the same time - maybe this would be the way to do it.
I'm not sure if there will be a problem wrapping the <form></form> around just the current variables on This Page. Maybe not. I think I may experiment with this, though...
Thank for your input on this.
Does seem like something like this, updates within NextPrevious pages would be a common practice and an easy fix doesn't it?
