[mapguide-users] Oracle Spatial v/s Oracle Locator with MapGuide FDO

[Andy Morsell]

I'm not intending to argue, but I still don't think that is correct about
indexing.  It looks like Locator supports the same indexing.  If it didn't,
it would be extremely slow.

Andy:

The information that I gave you was taken from Oracle Spatial 10g
Fundamentals training course, the common feature for both Locator and
Spatial is the use of Spatial Functions (not Operators).

The Spatial Indexing is not supported for Locator.

I think that both Locator and Spatial support the same R-Tree indexing so
the speed of Locator should be comparable to Spatial.

Hi:

The Main difference between Locator which comes with Oracle XE, SE, and EE
for free and Spatial (available only as Oracle Enterprise Option) is the use
of Oracle Spatial Indexes and also related to that the capability of using
Spatial Operators, of course the Spatial Operators and Spatial Index makes
Oracle Spatial faster than Locator.

Finally the type of geometry that Spatial can store is more complex and it
is a bigger set than Locator one.

That is great news about SL-King writing a native Oracle provider.  I can't
wait to see it.  I have found that trying to use the Autodesk Oracle FDO
provider with non-Autodesk created Oracle Spatial data can be an exercise in
frustration.

Paul is right, PostGIS is neither crippled or slow and his news that a
native FDO provider is just around the corner is great news for everyone.

On the Oracle front, Locator is all you need for use with MapGuide. Haris
Kurtagic an AutoDesk Partner in Bosnia is writing a native Oracle provider
that does not require the F_* Autodesk catalog tables (which the AutoDesk
provider shipped with their per pay version requires and which can only be
created via AutoDesk client side tools - part of the reason, I suspect, why
they are not shipped with the open source
version) as I write. I have seen Haris's work on integrating Autodesk Map 3D
and Oracle's Topology (an Enterprise Edition feature) was excellent so I
suspect his native FDO provider will be good. He is not sure about how to
market it.
I have suggested that he make it open source and he is thinking about it:  
I think that
there is more money in providing solutions to customers than writing
drivers!

If you need more "in database" functionality with Oracle Locator then as
long as you are not using XE you can drop Java functions based on JTS into
the database and call them  from PL/SQL. But that is quite a bit of
engineering when it is all there in PostreSQL/PostGIS.
