Need help on Oracle8i Spatial – Release 8.1.7.
I'm designing a spatial Oracle database using Oracle8i-Release 8.1.7.
Enterprise Edition. I read the documentation:
Oracle Spatial – User's Guide and Reference (a85337-01)
On page 28 f. (Chapter 1.2 Object-Relational and Relational Models) they
write:
You should select the object-relational model in all cases except where
the relational model is necessary for current needs. Basically, the
object-relational model is preferable in cases where replication and
distributed databases are not required. [...] In these environments,
users can take advantage of the Oracle8i managed standby capability to
get, in effect, read-only replication of database instances or
tablespaces, and thus the object-relational model can be used. [...]
1.2.2 Benefits of the Relational Model: The following are some of the
benefits of using the relational model, as described in Part II of this
* Database replication is supported.
I have to develop a distributed database and as I have to deal with a big amount of image data within this db I need to use replication. At least 'read-only replication'.
So my questions:
Is there a possibility for me to use the Object-Relational Model?
If not:
When is Oracle going to implement distribution and replication for the
ORM?
As I choose the relational model: How long this model going to be
supported by Oracles' new releases?
Please help
