We are using an Oracle 11g database with ArcGIS 10.1. I'm looking for some documentation on the descriptions of what the "User" and "Owner" roles do. For instance, when I create a feature class with my user name Leo.Plan.Zoning, what exactly does this mean? Is it a privileges setting? Also, we have a user account called "GIS", is this the "admin" sde account? Should all of our data be created and loaded with the GIS, DEFAULT account?
