[mapguide-users] Generate map tiles from Oracle data

Well, you'd still need to store the information in Oracle (in case you
make a change to the map definition and it invalidates your tile cache)
but using the Base Layer Group functionality in MapGuide would mean that
requests beyond the initial request would come from the tiles rather
than from Oracle.

Careful with this; if you add more than a couple base layer groups to a
map, you'll run into performance issues.  You may be better off trying a
nightly transfer of your Oracle roads table to SDF or SQLite formats for
improved read-only performance.

We have MapGuide serving maps using data held in Oracle spatial tables.
for example we have one table holding all the roads for the UK. What we
to do is create a set of tiles at various zoom levels for this data so
we can cease to hold the information in Oracle.
