Galaxy evolution is a complex process where both the inner evolution of stellar population, gas and dust, and the external effects, like interactions and exchanges with the environment, have to be taken into account. It has been fundamental in the last years to be able to build and use homogeneous catalogues both in the local and the far universe. The observation of galaxy morphology and kinematics as a function of the redshift is indeed necessary to disentangle the various galaxy formation and evolution scenarios. Some years ago, the hyperleda extragalactic database was designed to study the local universe from the point of view of both stellar populations and galaxies kinematics and dynamics. Today it contains homogeneous data for about 3 millions of galaxies, with for each up to 80 astrophysical parameters available. We will describe here the MIGALE project which emcompasses the HyperLeda databases plus a series of tools developed to study the dynamical, chemical and morphological evolution of galaxies. It will include, in particular, methods to analyse the GIRAFFE cosmological fields (IFU spectroscopy) and compare them with the Local Universe.
