Design and implementation of the spectra reduction and analysis software for LAMOST Telescope

The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) will be set up and tested. A fully automated software system for reducing and analyzing the spectra has to be developed before the telescope finished. Requirement analysis has been made and data model has been designed. The software design outline is given in this paper, including data design, architectural and component design and user interface design, as well as the database for this system. This paper also shows an example of algorithm, PCAZ, for redshift determination.
