CW2 TASK 3: Requiements
1. Each group should read and analyze the provided
documents, focusing at least on the disruption plans 1-19
and the stations issues of SWR West Journey.
2. Build a DB and KB based on these documents and using
one of the provided database schemas. Do not use
NoSQL
3. Build a UI to get information from a staff user about the
current situation (e.g. a line blockage) and return the
requested details of the appropriate contingency plan
and/or station disruption plan.
4. Devise some example cases to demonstrate the system.
Below gives the generic scenario.
