SDF is using SQLite as the storage engine.<br>
Unfortunately it changes the internal index structure of the SQLite
file.<br>
I'm guessing that this provides better performance.<br>
<br>
The change makes the SDF file unaccessible by regular SQLite database
tools.<br>
<br>
The proposed format will keep the SQLite filestructure intact, thus
making all SQLite tools compatible.<br>
It will likely be a bit slower (depending on the actual
implementation), but easy to access from non spatially enabled database
applications, through SQLite ODBC.<br>
<br>
>From my point of view, it will be a much better candidate for a
personal spatial database than SDF.<br>
The ease of data exchange between spatial and non-spatial applications
means a lot to me.<br>
Now if only there were providers for MapInfo and Arc.... :)<br>
<br>
If the provider is implemented with basic SQL statements, it should be
able to use any DBMS as spatial storage, not only SQLite.<br>

<pre wrap="">Hi all,
This maybe a stupid question but i tought that the sdf format was a SQLite
database.
Is that true?
If it is, what would e the difference between a SQLLite provider and the
actual SDF provider?

I just posted FDO RFC #16. Fresh off the virtual presses (printed on 100%
