The UI allows for the creation, search, modification, and deletion of nodes. As a rule, nodes should not be deleted from the database for referential integrity reasons -- even though there is only one table in the database, various processes use this table in concert with the flat files that contain the raw and analyzed PingER results.
How to access the UI for updating is described in Updating NODEDETAILS with SQLPlus.
Updating the list of countries in the UI
Inside the UI, the country and continent (region) are set and restricted to a pop-up list of values. The pop-up list is based on a separate table called COUNTRY. New countries can be added to the list by creating new rows in the COUNTRY table with SQL INSERT statements. See Updating NODEDETAILS with SQLPlus

The COUNTRY table is not used except by the list of values in the UI. Note that if a country name needs to be changed or if a country was placed in the wrong region, it must be updated on all the nodes in the NODEDETAILS table as well as on the COUNTRY table.
