  We provide, for non-experts, a brief overview of holographic QCD and a review
of a recent proposal of matrix-description of multi-baryon systems in
holographic QCD. Based on the matrix model, we derive the baryon interaction at
short distances in multi-flavor holographic QCD. We show that there is a very
universal repulsive core of inter-baryon forces for generic number of flavors.
This is consistent with a recent lattice QCD analysis for N_f = 2, 3 where
repulsive core looks universal. We also provide a comparison of our results
with the lattice QCD and the operator product expansion (OPE) analysis.
