Creating existing tables compared to creating new tables

It is important to understand the ramifications of creating a new proxy table and new remote table compared to creating a proxy table based on an existing remote table. If you create a proxy table based on an existing table and you decide to delete the proxy table, there is no effect on the remote table. However, if you create a new proxy table and remote table, when you delete the proxy table the remote table is also deleted.

If you create new remote tables based on proxy tables, consider naming the proxy table with a special convention that indicates that deleting it will delete the remote table.
