Query: Heavy flavor production in the STAR experiment   In this paper, recent STAR heavy flavor measurements in proton-proton and
heavy-ion collisions are highlighted. We report studies of open charm mesons,
reconstructed directly from hadronic decay products, and studies of electrons
from semi-leptonic decays of heavy flavor hadrons. We also present J/$\psi$
measurements via the di-electron decay channel at various collision systems and
energies. In Au+Au collisions the energy dependence of J/$\psi$ production
measured at $\sqrt{s_{NN}}$ = 39, 62.4 and 200 GeV is shown. Finally, prospects
of heavy flavor measurements with the STAR detector upgrades are discussed.
