In web application that has multiple tabs in a single form, use one save button to save all tabs or multiple save buttons

We have a SPA web application, and in some forms there are multiple tabs that show data related to a single parent Entity (Like if we have a student main entity and we have for him 5 or more tabs that shows information about the student as demographics, registration, fees, addresses, etc...)

Should I use one save button that saves all the information in all tabs in single action or It is better to include in each tab a save action that saves that tab information.

Thank you,
