Tracking Rise 360 Learning - Sharepoint or alternative?

Sharepoint can be set up to act as a webserver, so it could be used to present courses. But to track quiz scores and/or course completions, the Articulate software needs a place to store the course info for each learner. That place is an LMS or LRS. Those are designed to accept the data (or, rather, Articulate software is programmed to provide the data in a way that an LMS or LRS can use). 

This 2018 blog from Tom Kuhlmann describes how to track completion without an LMS. But it doesn't provide the same quiz data that an LMS or LRS would.
