This paper is organized in the same way as the lectures given by the authors at CIMPA’s school ‘Topics in non commutative geometry’. The authors first recall the main results concerning deformation quantizations theory and star products. The notion of Morita equivalence is then explained in detail. Then the authors describe the Morita equivalence for star product as orbits of a suitable group action. The B-field action on formal structures and the Morita equivalence via Kontsevich’s classes are then studied.
