...As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code, each installation optimised for a certain kind of DB; 2. be a stack of core black boxes to provide general DBMS functionality, plus a range of plug-in black boxes to support different physical storage mechanisms & scalar data types; 3. employ code designed with a mixture of functional, OO & other methods so as to minimise internal DBMS state complexity. The 'Northumbria Website' (above RHS menu option) describes the vision, specification & design of the RAQUEL language & DBMS architecture.

A program that gather trains delays data, so as to make user able to make statistics. Delays are published by train companies, but only the current day is available. Open Delays intends to gather this data in the longer term, so users can have a statistical vision on the train they use, and control and identify structural problems in train exploitation. This also allows to know for example if the train you are stepping in had 15mn delay in 30% of the cases : if you have this kind of information, you know you will have probably a delay.
