I was actually thinking exactly the same thing.  Part of the reason I use 
PostgreSQL for all my bioinformatics work is that there is a need to correctly 
associate analysis results with the data and experimental methods they come 
from.  I have tables for experimental runs, technicians, procedures, samples, 
drugs, etc. and I use foreign key constraints to connect them all.  The idea is 
to have all the information readily accessible to reproduce complex results in 
modern scientific fashion.  If I store the plots in the DB, I can connect them 
to all these basic information tables.
