Databases in investigation of the world of ancient objects: technology and possibilities

Material objects are viewed as sources of hidden information. The source must be transformed to extract this information. As a result, a new version, or model of material source arises. In the seminar "Morphology of antiquities" headed by Yu. L. Shchapova a system model of material sources' description has been worked out. It assumes that statistical determination of indication weight should follow its logical analysis, which lets revealing hidden factors ruling the evolution direction in the selection under investigation, and thus enables transition from searching "a working indication" to revealing a working subsystem. This principle is shown on various categories. Database is presented as a series of tables aimed at revealing "a working subsystem" each.
