Digitale Datenbanken: Eine Medientheorie im Zeitalter von Big Data

Wir leben längst nicht mehr nur im Informationszeitalter, sondern in der Ära von Big Data. In dieser steht die Datenbank gleichzeitig für die riesigen Erkenntnispotenziale von Informationssammlungen wie für die bedrohlichen Informationsexzesse der digitalen Medienkultur. Zudem bezeichnet der Begriff konkrete Technologien und Verfahren der Sammlung und Bereitstellung von digitalen Informationen. Zwischen diesen sehr unterschiedlichen Auffassungen gilt es, Datenbanken medientheoretisch zu verorten. Marcus Burkhardt zeichnet die Geschichte der Datenbanken nach und fragt, wie technische Verfahren der Verwaltung digitaler Informationen bedingen, was auf welche Weise in Datenbanken gefunden und durch sie gewusst werden kann.We have long moved on from a mere information age to the era of big data. Here, databases represent both the enormous potential for gaining knowledge of data collection and the alarming information excesses of digital culture. Furthermore, the term refers to concrete technologies and processes of gathering and accessing digital information. Media theory has to locate databases in between these very different conceptions. Marcus Burkhardt retraces the history of databases and asks how technical procedures of processing digital information determine what can be found how in databases and what knowledge can be gained through them

VIRTUAL INFORMATION IN DATA-BASE SYSTEMS

This paper examines the concept and implications of virtual information in data base systems. Virtual information is any fact which does not physically exist in the data base, but is nonetheless accessible through combinations of algorithms and other data. Physically recorded information is only one of a num-ber of ways to obtain information from a data-base system. View-ing an information system as a collection of functions shows that pure data and pure algorithm from the endpoints of a spectrum of ways function values can be realized, with the middle range being various types of virtual information. Several classes of virtual information are identified, and their usefulness is examined to show the appropriateness of the cor~cept in a data-base system. Finally, the model is evaluated in light of the implications of virtual information for inference and automatic restructuring within a data base
