  \textquotedblleft Stark" broadening theories and calculations have been
extensively developed for about 50 years and can now be applied to many needs,
especially for accurate spectroscopic diagnostics and modeling. This requires
the knowledge of numerous collisional line profiles. Nowadays, the access to
such data via an online database becomes essential. STARK-B is a collaborative
project between the Astronomical Observatory of Belgrade and the Laboratoire
d'\'Etude du Rayonnement et de la mati\`ere en Astrophysique (LERMA). It is a
database of calculated widths and shifts of isolated lines of atoms and ions
due to electron and ion collisions (impacts). It is devoted to modeling and
spectroscopic diagnostics of stellar atmospheres and envelopes, laboratory
plasmas, laser equipments and technological plasmas. Hence, the domain of
temperatures and densities covered by the tables is wide and depends on the
ionization degree of the considered ion. STARK-B has been fully opened since
September 2008 and is in free access.
  The first stage of development was ended in autumn 2012, since all the
existing data calculated with the impact semiclassical-perturbation method and
code by Sahal-Br\'echot, Dimitrijevi\'c and coworkers have now been
implemented. We are now beginning the second stage of the development of
STARK-B. The state of advancement of the database and our program of
development are presented here, together with its context within VAMDC. VAMDC
(Virtual Atomic and Molecular Data Center) is an international consortium which
has built a secure, documented, flexible interoperable platform e-science
permitting an automated exchange of atomic and molecular data.
