Databases, Data Warehousing, and Data Analytics

The ongoing and rapid transformation of their markets presents media companies with the challenge of further digitizing and sustainably adapting business models. For this purpose, a broad technology stack for aggregating, storing, and analyzing big data is gaining importance: By means of the big data value chain, polystructured and multimodal data are combined with each other, and analytical insights are obtained in batch and real-time processing. For this purpose, different database systems as well as methods for data analysis (text mining, audio mining, and video mining) are combined in a generic lambda architecture. This makes it possible to leverage potential benefits in the production and distribution of media content, as the chapter outlines using the examples of the Deutsche Presse-Agentur (dpa)/Deutsche Welle (DW) and Netflix.
