The past two decades have seen an important progress in the research field of 3D imaging of the partonic structure of nucleon with the emergence of the Generalized Parton Distribution (GPDs) formalism and its associated experimental programs. GPDs conceptually introduces in connection with the partonic description of deeply virtual Compton scattering (DVCS) and deeply virtual meson production (DVMP). As with parton distributions, flexible phenomenological parameterizations of GPDs are essential for their extraction from data. In this talk, I will present an introductory to GDPs. Furthermore, I will review the status of the theory and phenomenology of hard exclusive processes. Finally, I will show that our simple physical model of input GPDs used in conjunction with two modern parameterizations of proton PDFs (CJ15 and CT14) provides good description of the H1 and ZEUS data.
