Admin-Tool

The admin-tool is necessary for fostering and maintenance of the web-based XML data stored in a MySQL database queried by php. The radiomap application is an „empty shell“ loading all the current data every time it starts from the server. I outlined the affordances and Stephan had the idea for the admin-tool and conceived the intricately interdependent database structure.

The different values as stations, genres, formats, cities, countries and languages are heavily interdipendant. E.g. Bengali stations in Chicago, USA. We have streaming audio (formats qt, wmv, ra, mp3) from radio-stations (name, genres, language) > in cities (name, Lat/Lon) > in countries (name) etc.

The Admin-Tool consists of eight different editor-areas (windows):
Stations (main-window) + Station-Genres, mediatypes, genres, languages, countries, cities, map,

Stephan Huber developed the structure of the database from the requirements outlined in the concept. This is the documentation.
