  Massive stars condition the evolution of the interstellar medium by the
amount of energy released during their lives and especially by their deaths as
supernova explosions. The vast amounts of spectroscopic data for massive stars
provided by previous and existing instruments on ground-based and space-based
telescopes have already saturated our capability to process them by the use of
human routines. As a consequence, there is a pressing need for machine-assisted
tools to help handle incoming data. To this end, we present the development of
a massive star spectroscopic multiwavelength interactive database designed for
scientific research and a fully automatic stellar parameter determination tool.
Here we show the preliminary results of the application of these tools to
optical spectra of O-type stars.
