The fully operational version of the world's principal database of binary and multiple systems of all observational types is presented. The Binary star DataBase, BDB, is available at http://bdb.inasan.ru and is created as a source joining the comprehensive information on binary stars of all observational and evolutionary types. It provides the user with synthesis of data of large variety of catalogues and databases of binaries of different types: visual, orbital, astrometric, eclipsing, spectroscopic, photometric, etc. The BDB contains all data from catalogues on about 50,000 stellar systems of multiplicity 2 to 22: positional, photometric, spectroscopic, orbital and astrophysical parameters are provided when available. Organization of the information is based on the careful cross-identification of the objects. This allows the user, in particular, to search data on binaries having certain sets of parameters within the complete catalogued data set.
