  The paper presents the basic principles of formation of a database (DB) with
information about objects and their physical characteristics from observations
carried out at the Crimean Astrophysical Observatory (CrAO) and published in
"Izvestiya Krymskoi Astrofizicheskoi Observatorii" and other publications. The
emphasis is placed on DBs that are not present in the most complete global
library catalogs and data tables - VizieR (supported by the Strasbourg ADC).
Separately, we consider the formation of a digital archive of observational
data obtained at CrAO - as the interactive DB related to the DB of objects and
publications. Examples of all the above DB as elements integrated into the
Crimean Astronomical Virtual Observatory are presented in the paper. The
operation with CrAO database is illustrated using tools of the International
Virtual Observatory - Aladin, VOPlot, VOSpec jointly with VizieR DB and Simbad.
