multiple step forms

hey everybody,

i would like to ask about a module that would create for me a multiple step form for me in drupal and store them in the database, also with the ability to save the data inserted so far at each stage. ie if there is a 3 steps registration form : step 1 -personal , step 2 address , step 3 other info. i want to the user to be able to navigate the form as a step by step process. whenever he fills a form he goes to the next , and the first form is now saved in database and he can refill the rest later and the info he entered will not be lost. i want this to use it for a university registration system. any one knows how to do that ?

i need a simple walk through form with ajax and save at each step capabilities.

thank you very much :D
