Just trying to get a better understanding.

One other thing in relationship to this:

I see the relationship between these two files - what I should have said is
how does the point in this shape file get related to polygon layer over
which it is placed:

Here is a small piece of the polygon layer that my point layer is being set
on:

I have this simple shapefile:

File Bounds: ( 6471392.899,  282843.628,0,0)
         to  ( 8433025.828, 2304680.124,0,0)

Shape:0 (Point)  nVertices=1, nParts=0
  Bounds:( 7750718.722, 1391592.674, 0, 0)
      to ( 7750718.722, 1391592.674, 0, 0)
     ( 7750718.722, 1391592.674, 0, 0)

Shape:1 (Point)  nVertices=1, nParts=0
  Bounds:( 6471392.899, 2304680.124, 0, 0)
      to ( 6471392.899, 2304680.124, 0, 0)
     ( 6471392.899, 2304680.124, 0, 0)

Shape:2 (Point)  nVertices=1, nParts=0
  Bounds:( 8433025.828,  282843.628, 0, 0)
      to ( 8433025.828,  282843.628, 0, 0)
     ( 8433025.828,  282843.628, 0, 0)

Shape:3 (Point)  nVertices=1, nParts=0
  Bounds:( 6862716.092, 1226032.862, 0, 0)
      to ( 6862716.092, 1226032.862, 0, 0)
     ( 6862716.092, 1226032.862, 0, 0)

Shape:4 (Point)  nVertices=1, nParts=0
  Bounds:( 7249022.321, 1677559.623, 0, 0)
      to ( 7249022.321, 1677559.623, 0, 0)
     ( 7249022.321, 1677559.623, 0, 0)

And it relates to this dbf file:

7750718.72:1391592.67:Fred Flinstone
6471392.9:2304680.12:Jeff Jackson
8433025.83:282843.63:Trueman Polygonas
6862716.09:1226032.86:Alfred Espinoza
7249022.32:1677559.62:Jim Apple

I can bring this layer into place over my main map file and I see the
points. What I do not see is the relationship between the xy coordinates in
the dbf file and the Bounds in the shape file.

Can someone give me an understanding of this?

Thanks.
