A new base of template integrated spectra is presented, with a good temporal resolution, to be used for future determination of fundamental astrophysical parameters of Galactic and extra-Galactic stellar systems. New observational data of Galactic open clusters are provided, which allow to widen the current global knowledge of the Galactic open cluster system. The dissolution rate of these systems in selected regions of the Galaxy is examined. Reddenings and ages of 24 concentrated star clusters of the Small Magellanic Cloud (SMC) are also determined.
