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.
