[Qgis-user] Fwd: "Normal" mdb support possible for "normal" people?

[Randal Hale]

I don't know all the reasons for Access Geodatabases but here is what I 
do know.

When ArcINFO started turning into the desktop product there was a move 
to get things into a "database". ESRI had used INFO/Coverages for years. 
I think the quickest way to get to that end was Access. You could fold 
all your vector data into Access. It is slow from ArcGIS. You can't 
store raster. It has the habit of becoming very large very quickly and 
imploding. I think somewhere between 500Mb and 2 Gb were the problem 
sizes. They introduced file based geodatabases which aren't databases 
and aren't file based - they are directories and in my opinion are 
coverages Part II. File based databases are stable and much easier to 
work with - and too proprietary for my tastes now. You can get the data 
out but it isn't easy.
