Application configuration (database options)

An application configuration is a set of hierarchical options, where each option may get a value and any number of sub-options. Application configurations are stored in the application database. Options in a configuration are identified by an option name ( key ), which must be unique within each option list (or sub-option list), but not within the hierarchy.
