Query: A Course on Noncommutative Geometry in String Theory   In this pedagogical mini course the basics of the derivation of the
noncommutative structures appearing in string theory are reviewed. First we
discuss the well established appearance of the noncommutative Moyal-Weyl
star-product in the correlation functions of open string vertex operators on a
magnetized D-brane. Second, we will review the most recent attempts to
generalize these concepts to the closed string moving in a nongeometric flux
background.
