Name and Shame
"So the system, for some peculiar reason, holds multiple representations of the same data? If true, that would be an accident waiting to happen."
In my day, the data for a small group of people was centralized in a PERSON, who took register, noted the reasoning and adjusted accordingly.
So for example it (or rather 'she') would *not* send out a letter if the child had Leukemia and was often away... you know, H-U-M-A-N interaction, the flexibility of people.
It didn't need a special flag for a special exception, because the teacher could handle all special exceptions using a very flexible thing known as a brain.
I notice Brown is always "name and shame", his response to everything is to "name and shame local councils who....", "name and shame failing schools who..."
And that this is often built into the automated systems and even in the attitudes of the people who run them. Even the government adverts constantly threaten and harrass (e.g. you can now pay your car tax by phone, or your car will be crushed).
Automated systems that send out threatening letters are the norm for Britain and when people complain, the downtrodden people whose lives are sh*t tell them to shut up, enjoying the fact that someone else life is as sh*t as theirs is.
What kind of a life is that? Joyless people making each other unhappy to drag others down to their own level of unhappiness?
IMHO, They should stop sending out automated threatening letters, when someone is absent, they should ask the person's teacher to investigate or telephone, or explain about the death or the Leukaemia or whatever. People should treat each other decently.
Same goes for the 'squeal on your neighbour for your own suspicions' Jacqui Smith stasi idea.
Same goes for the attempt to replace people with Biometric measuring computers and 'behavioural analysis software'.
Same for every government department that sends threatening letters as the first default for every little thing their computer tells them is wrong.... do you ever imagine the fault is in your computer? Or the data it has? So why is the default to blame others?
