I confess...databases scare me.
The ONLY database I ever used (and loved it!) was a DOS program back in the '80s called FrEd Base -- Free Educational Database. It was SIMPLE, intuitive -- not intimidating.
A couple times I've played with LibreOffice's database. How good is it? I wouldn't know. Within two minutes I need an antacid.
BUT I again had occasion to wish for a simple, intuitive database -- and found one: Symphytum. I downloaded the 64-bit debian version to my laptop running FossaPup and within minutes I was starting a database. Like I said, it's pretty intuitive. It's available for Linux (Debian, Arch, AppImage, & Snap), Mac, Windows, and has MEGA cloud support. If it's a concern to anyone, it looks like it might not be maintained anymore (???); the last update was February 2020 (so if you plan to use it, keep a copy of the the installation file!).
CAVEAT: This isn't a recommendation but a referral. I have NOT given it a thorough testing, I've just begun a database of some student records and only have maybe a half-dozen so far-- SO experiment, give it a workout for yourself, and see if it fits your needs! That said, I'm pretty happy!
