Hi folks, I've got a question regarding inheritance. What are the advantages of using inheritance in the database structure as opposed to using foreign keys? Doesn't interitance mean that there will be much more duplication of data in the database? If anyone has any examples of proper usage of inheritance, please let met know. I've read the docs, and haven't puzzled out the usefulness of inheritance. Thanks, -- Mark Steele Vice president research and development Inet Technologies Inc.
