The database is a repository for various graphical and non-graphical objects that form a drawing. These objects have different types, sizes, destinations, functionality, and specifics. A drawing loaded from a file can contain different information about objects that define the geometry, styles, representations, settings, attached data, and custom objects. Objects of the database are organized in collections.
