National Institute for Fusion Science Japan has constructed the atomic and molecular numerical database for cross sections of various collision processes such as ionization excitation and recombination by electron impact since 1980s. Such atomic data are important for diagnostics and modeling of plasmas. Excitation by electron impact between excited states of ions is one of key processes which determine spectral line intensities in high temperature plasma. For X-ray astronomy spectroscopic diagnostics is an important basic tool to get information of physical properties of objects and plenty of reliable atomic data are required. We collect atomic data and provide them to researchers as the database. The database is available at http://dbshino.nifs.ac.jp/ and registration is required (free of charge). The atomic data are retrievable and numerical data tables and graphs can be displayed in a browser. The database will extend to include ionization and excitation rate coefficients which can be used directly in models for diagnostics and others. Understandings and help by atomic physicists are essential for our database activities. We thank all the help in past and would be grateful if atomic physicists provide their new data to our database.
