Managing properties in the database using manageProperty API

The manageProperty API is used to create, modify or conditionally delete a property from the database.

The default Operation for the API is Manage, which acts as Create if the specified property does not exist, and acts as Modify if it does exist. Before creating an override, the BASE property must be defined. You cannot delete a SYSTEM property. When deleting a CUSTOM base property, all the overrides for this property are also deleted.
