Yes, some of it would be but the relationships between entities would be

No, this is exactly what I need for this kind of project. Lots of people have
to access the data for many different things (material take-off, detailing,
production, shipping, tracking, billing) so making it available allows me to
spend more time on the production process and less time helping other people
do their job. Currently, we are using a dwg file for storage of most of the
data (mostly geometry, but also some controlling data) and it is all very
highly organized (4500 layers). In addition, I've got about 60 config files
involved. If anyone else can access these without asking me where they are
or what they mean (%length = ("attachment" => 60, etc...) then we will all
save a lot of time.
