EDIT: You don’t have to answer for my specific purposes, if you use a database for any purpose yourself then please share and tell what and why.
I’m not planning to host any fediverse or mastodon instances just yet, but maybe a private email server and porting a discord channel to matrix might be in my future.
What do you use and why? Is it limited to a specific OS, and if you were on a different OS then what would you be using instead? Do you think server hardware is required for most operability or can a good desktop computer and internet speed suffice as long as downtime isn’t a problem?
You may have missed the point of the example. It asks about steering wheels, and immediately transitions to vehicles that don’t have steering wheels.
Are you implying that databases don’t exist for private email and hosting a matrix channel? Because if so then you’re just blatantly wrong.
What do you even think a database is?
