Creating form and collecting data inside SharePoint

Greetings,

I’m pretty new to SharePoint but very excited to learn as much as I can about the platform.

I’m currently looking to create a 4-part online application/form that will save the data to a file/database/list on my SharePoint site.

When I say 4-part application, I mean, for example:

Part 1 – personal info
Part 2 – References
Part 3 – Experience
Part 4 – Education

After one section is done, a “next section” button can be clicked. The sections would have to be linked by a common field (id perhaps). 

Have 4 different sections is actually secondary. The important thing is to have an online form, accessible in the browser, where applicants can apply and the data gets saved to a file (.app, .xls, .csv, etc.) on the SharePoint site.

I appreciate any help or guidance.

Thanks in advance
