Haben Sie schon einmal ein Business Intelligence (BI) oder Analytics Projekt von Anfang an begleitet? Dann wissen Sie sicher wie aufwendig die erste Phase (Datenzugriff und Datenaufbereitung) sein kann. Marktanalysten schätzen das Verhältnis Vorbereitung der Daten zur eigentlichen Auswertung auf 80:20. Das heißt, im Normalfall wird der weitaus größte Teil der

During the review, a chart was shown to summarize the status of IoT projects in the manufacturing sector. I wasn’t surprised by the varying degree of “completeness” of IoT projects across this industry, but
The metaphors we choose to describe our data are important, for they can either open up the potential for understanding and insight, or they can limit our ability to effectively extract all the value our data may hold. Consisting as it does of nothing but electric potentials, or variations in
Hadoop has been called a game changer technology. Here’s why: - DATA IS DIFFERENT: We now have to deal with both structured and unstructured data. - NO LIMITS: We now deal with Terabyte or Petabyte data size and not just with old Megabyte. - COMPLEXITY: We work with complex multi-server
