Why Do Companies Need All That Personal Data They’re Collecting?

It’s the Tech perspective, but has the potential for a good debate. Under GDPR it’s not even compliant and still plenty of companies collect all data they can get hold of. Driven by Big Data vendors telling the narrative of Data Lakes, that only require you the data today, should you want to ask any question you don’t know yet in the future.

Only – have you ever come up with a question that you could not answer based on the data that is already available? Based on data that you collected in a Data Lake?

Big disclaimer: personally I don’t conclude with the assumptions made in the initial article, but the question is worth thinking about. In particular because most organizations I met until today are not metric driven in first place.

Not so big data.

Chris Stucchio hat einen interessanten Punkt bzgl. Big Data. Nämlich, dass Big Data heißt gar nicht Big ist. Nur weil Excel einen Datensatz nicht öffnen kann, heisst das nicht automatisch, dass Big Data Tools – in seinem Aufsatz Hadoop – notwendig sind. Gigabyteweise Daten lassen sich auch anders verarbeiten. Moderne Hardware hat nicht selten mehrere GB an Hauptspeicher. Die Geräte bei Mediamarkt waren vergangenen Samstag alleine mit mindestens 8Gb ausgestattet. Das heisst natürlich nicht, dass Hadoop oder vergleichbare Tools gar keinen Anwendungsfall hätten, aber die Use-Cases sind vielleicht anders gelagert, als man auf den ersten Gedanken annimmt.
