Basically, the database will be used to build up an engineering document
called a P&ID which traditionally comes in the form of a drawing. From the
database I'll create a drwawing which the user can, if he wants, convert
into a DXF file for use in AutoCad or Bentley drawing systems.
The database will also be used to transfer information to other engineering
databases yet to be completed.
