-Test suite for PL/pgSQL
-
-Scenario:
-
- A building with a modern TP cabel installation where any
- of the wall connectors can be used to plug in phones,
- ethernet interfaces or local office hubs. The backside
- of the wall connectors is wired to one of several patch-
- fields in the building.
-
- In the patchfields, there are hubs and all the slots
- representing the wall connectors. In addition there are
- slots that can represent a phone line from the central
- phone system.
-
- Triggers ensure consistency of the patching information.
-
- Functions are used to build up powerful views that let
- you look behind the wall when looking at a patchfield
- or into a room.
