I am currently working a bioinformatics internship, and I'm fairly new to all of this. Right now, I need to learn about the different databases and interface with them, using gene sets as the input to these databases.
I've noticed that the ones I'm looking at, GO and KEGG, give out different results--while GO has the three different categories (biological processes, molecular functions, cellular components), KEGG appears to give out results based on pathways? It makes me sort of nervous to get results back from GO and then get only one significant result from KEGG.
I know GO and KEGG are not the only databases out there, so I'm interested:
Can someone give a brief summary over the nature of some of the major databases' "output?"
