Managing Attribute Table in Oracle GDB

Hi every body
I want to separate the attribute data and feature classes. for this I have to create additional tables for each class.
how to proceed to:

1. Manage thesetables independantly from classes (insert, delete, update, query) of records?
2. link a record created on map ton its corresponding record in the attribute table.?
3. publish the table as a service to manage it in flex viewer for exemple.?

is it possible ? if yes how ?
else how can i do this in different way ?

thx
config: arcgis (server/desktop)10.1, oracle 11g.
