DataBase Representation

I need to develop an application that needs to show Database tables and the
connections between them. I haven't been able to find graphic objects that
simplify my work. I need your help in finding graphical objects that will
allow me to show tables, connect them, give the user the ability to move
around these tables and also Zooming and scrolling capabilities.
Thanks

consider using Visio by Visio Corporation. It was one of the first products to support automation. From your description it seems to have all the features you need (connecting elements and so on).
