DAD is a connections manager used in many industries to design and manage systems.

Traditionally you make drawings and then collate them to extract information.  DAD reverses this process, now you enter your system information into DAD and then publish the documentation (and drawings) required.

The reversed process delivers:

• improved accuracy.  The information is inherently coherent 
• increased productivity.  There is none of the usual duplication of data
• faster access to information because it is all in the DAD model.
