  We present an alternate deployment of the GrayStarServer (now
ChromaStarServer (CSS)) pedagogical stellar atmosphere and spectrum synthesis
WWW-application, namely ChromaStarDB (CSDB), in which the atomic line list used
for spectrum synthesis is implemented as an SQL database table rather than as a
more conventional byte-data file. This allows for very flexible selection
criteria to determine which transitions are extracted from the line list for
inclusion in the synthesis, and enables novel pedagogical and research
experiments in spectrum synthesis. This line selection flexibility is reflected
in the CSDB UI. The database extraction is very fast and would be appropriate
for the larger line lists of research-grade modeling codes. We also take the
opportunity to present major additions to the ChromaStar and CSS codes that are
also reflected in CSDB: i) TiO band opacity in the JOLA approximation, ii)
Metal b-f and Rayleigh scattering opacity, iii) 2D implementation of the flux
integral, iv) Improvement of the N_e convergence, and v) Expansion of the
exo-planet modeling parameters, and vi) General improvements to the UI. The
applications may be found at the home page of the OpenStar project:
