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

[Andrea Peri]

Yes is true.
Esri don't recommend the personal-gdb.
Esri recommend the arcsde version.

Because the access db is slow and with size limit (2GB).

The spatialite instead has not a size limit and is fast. :)

But I guess there is another more important question:
spatialite work in double precision indipendently by the extent of the DB.

In the personal-geodatabase (9.1 version) is the extent of dataset is 10km
there is a precision P1.
If the extent of the dataset is 1000Km the precision is P2 with P2 worst
than P1.

Spatialite don't do this.
