The many benefits in this kind of management are here exposed, in particular if a connection to a WAN (Internet) is available. For construction, the system allows to operate in conformity with the ISO 9000 standard. The constitution of a central database is the fundamental aspect: daily data collection is concentrated and made accessible to all the clients, thus reducing redundancies and increasing efficiency. This is particularly evident when a cross-check among measurements performed with different methods is necessary, as in the reported example on beam measurements on a Tomotherapy® device. A procedure is introduced to correctly read the discrepancies, from a web-management point of view, among measurements performed with Tomotherapy® Xe on-board detectors, Tomodose® and ion chambers. Data collected with different measurement methods are analyzed and compared in real time. The database remains available in order to build time trends that can be useful for forecasts
