Host a database alongside HA?

I have HAOS installed on a NUC.
I would like to have some kind of a database installed on the same machine.
Is this possible? If so, how?

I have racing pigeons. And when you have around 70 pigeons that the hawk feeds on, and that you constantly have to breed new ones for. Then paper and pencil are no longer enough to keep track of all the pigeons :grin:.
So I thought of setting up some kind of database where I can store all the information. But I have no desire to set up a separate computer and pay for its running costs for such a small task.
And since my HAOS is constantly on, I was hoping someone has a solution to host a db on the same machine.
