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.
