Thank you. i ran uhd_spectrum_sense.py and it helped alot. I am now in the process of getting it to also print out the location in longitude, latitude, and altitude.

That doesn't necessarily answer the question about schema - you could
have a whole bunch of columns, one for each frequency bin across a
band, or a shorter record of power level on a frequency at a
particular time.

Have a look at uhd_spectrum_sense.py for a start. It emits text
records with many of these measurements - try write a script to parse
the output and stash it into a database. When you get that working
you'll probably understand how to add database logging to
uhd_spectrum_sense.py.
