DBCONNECT
Provides an interface to external database tables.
Link Database Records to Graphical Objects
Links connect graphical objects with tables in an external database.
Create and Edit Links and Link Templates
Each link requires a link template, which identifies what fields from a table
are associated with the links that use that template.
The primary function of the database connectivity feature is to associate
external data with program graphical objects. You can, for example, associate
information contained in a room database with a polyline object representing
a room boundary in a drawing. You establish the association between the
graphical object and the database table by creating a link, which references
one or more records stored in the database table. You cannot create links to
nongraphical objects such as layers and linetypes.
Links are tightly connected with the graphical objects they are associated with.
If you move or copy a linked object, the link is moved or copied with it. If
you delete a linked object, the link is also deleted.
When you create a link, a dynamic relationship is established between the
database record and the object. If, for example, you convert a room from a
storage area to an office in the database table, the program provides a
mechanism to update the information stored in the drawing so that it matches
the database table.
