Not really Landon, to understand how an ESRI Shape dataset works all the
documentation you need is in.
http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf
That is going to tell you about the records descriptions and the order that
they occurs in the ".shp" binary file for each feature type (points,
polylines, polygons, etc.)
But instead of that you should use Warmendan's ShapeLib to make it works,
whatever you are trying to develop. If you are...
http://shapelib.maptools.org/
To reduce the pressure on understanding the dBase files, in my opinion the
".shp" and the ".dbf" can be treated as if they are independent. You just
need to check that a shape feature X must have a row X in the dBase table.
The dbase fields are all descriptive attributes of that geographic feature.
That's all.

Subject: [gislist] Shapefile DBF Specification
I have read through the shapefile specification available from ESRI, but
I was hoping to find a specification or document that explained the dbf
file format. I think this is key part of understanding how a shapefile
works. Does anyone have any suggestions?
Thanks,
The Sunburned Surveyor
