# Timetable Informationsystem

The online timetable of the SBB (Swiss Federal Railways) is an example of a web based information system founded on a database system from the bounds of public transport. Its main task is to inform the users with current and correct information about the best connections and the train operation of the SBB at any time.
The most important characteristics of such a database system:

Concurrent Use | The database system of the SBB timetable can be used by different users and applications concurrently. While the information are used internally within the SBB, information about the timetables and other specific information can also be used from the public via the internet.

Data Integrity | The users of the SBB timetables need current and correct information at any time. This makes great demands on the data integrity. Therefore, timetable or platform changes or any other changes need to be updated constantly in the database system.

Such a database system can get more than one call per second in record times. Therefore, perfomance is also a very important characteristic which was not mentioned above.
