[Zope] Oracle access from Zope

I am evaluating Zope, and I would like to know if there is a Zope database driver for Oracle? Is there a documentation about the services of this driver? Recently, I have been evaluating several Oracle database access interface modules for Perl, Tcl, Python, and found an interesting thing: none of these modules support calling PL/SQL procedures having array arguments (I do not speak of records or array of records because even OCI does not support record arguments). What about the Zope - Oracle module? It is very important in our case, because in our application array-argumented PL/SQL procedures are heavily used for efficiency reasons (they are really quite fast). Miklos Nemeth IQSOFT
