Projection in Google Earth and Oracle

Question

I'm trying to build a demo with dutch data (The Netherlands) with the article from Justin Lokitz http://www.oracle.com/technology/pub/articles/lokitz-spatial-geoserver.html. In his tables he uses SRID 8265. Anyone any idea which srid I should use with my dutch (Navteq = lat/lon) data?
And does anyone have any idea why the maps of The Netherlands or Belgium or whatever in Google Earth (or Mapinfo) is straight up, and the map of the Netherlands with geodetic data always looks tilted and stretched?

Generally CS transformation is rather straightforward, although sometimes mathematical complicated. Most of the times CS transformation to projected coordinates is a two step approach.
First from WGS84 (lat lon) to Local geodetic datum (lat lon), Secondly a projection is applied to local projected coordinates.
For the first step, if available, a 7 parameter transformation is applied. These parameters will give you the 3 translation, 3 rotation and 1scale factors from and to WGS84 to your local datum.
This first step is actually a 4 fase traject.
from WGS84 (lat lon) to WGS84 (X,Y,Z) then the 7 parameter transformation is applied to get YOURDATUM (X,Y,Z). After this you go from YOURDATUM (X,Y,Z) to YOURDATUM(LAT, LON).
The second step will apply the projection on YOURDATUM(LAT,LON).
I would think that this general approach counts for a lot of transformations implemented. although there are some other transformations available, depending on the availability of the 7 parameters.
