Experiments involving high-throughput methods for measuring transcripts, proteins and metabolites constitute the area of functional genomics. These experiments are highly context dependent and require much more detail about the experimental design, sample and protocols used than in genomics. Functional genomics databases are needed that follow established and emerging standards. Functional genomic databases are not yet very common; however, there are a few focused on microbial genomes and a couple integrative systems are available for setting up functional genomics databases.
