Hi Klaus,

actually object relational is not relational and not OO.

Additionally you have to face that you cannot alter existing types in the way you know it from
relations (this is actually included into the syntax but not implemented -- alter type ...)

If you have the possibility you should not use the object relational database, because it is
too new at the moment. It is something like a beta release. It is great to play with it,
but if you are interesting in a reliable DB, pure relational is the better choice.

Unfortunately I currently have the problem with freeing cache of opened cursors, that
cannot be freed although the interface has methods for it (CacheFree, SetCacheMin, ...)
The ODD C++ Interface does not work, and going down to OCI does not help.
