This eights Data Quality World Tour blog post is about Iceland.
Rather than using family names, the Icelanders use patronymics. This means that the first Icelandic President Sveinn Björnsson must have been son of Björn and I guess current Prime Minister Jóhanna Sigurðardóttir is the daughter of Sigurð. This must create some havoc for well proven algorithms for finding households. (Add to that that the Prime Minister is in a same-sex marriage).
In the good old days air traffic wasn’t concerned with the recurring volcanic eruptions on Iceland. Today it seems to be a repeating cause of travel havoc. A bit like poor data quality wasn’t taken seriously in the good old days, but today dirty data creates havoc in business intelligence implementations.
