In den letzten Jahren ist die Abhängigkeit von der Informationstechnik (IT) derart gestiegen, dass heutzutage kein Unternehmen mehr ohne sie auskommt. Vielmehr ist die effektive und effiziente Nutzung der IT zum entscheidenden Wettbewerbsfaktor im globalen Markt geworden. Dabei geht es um Arbeitsprozesse die in vielen Fällen bereits elektronisch gesteuert und überwacht werden. Große Mengen von Informationen sind digital gespeichert, werden zielführend verarbeitet und in Netzen übermittelt, so dass ein gemeinsamer, standort- und geräteunabhängiger Zugriff ermöglicht wird. Dieses erlaubt intensive Formen der Kooperation über geographische Grenzen hinweg, verdeutlicht aber gleichzeitig auch die Abhängigkeit von derartigen Datennetzen. Das gleiche gilt für die drahtlose Kommunikation der verschiedenen kleinen und kleinsten IT-Einheiten untereinander, die mittlerweile in alle Bereiche des beruflichen und privaten Alltags integriert werden. In einer derart digitalisierten Gesellschaft sind die verschiedenen Institutionen in Wirtschaft und Verwaltung stark von dem einwandfreien Funktionieren aber auch von einem gewissen Verständnis für die eingesetzte IT abhängig. Genau hier setzen die dreizehn Beiträge dieses Buches an mit dem Ziel, einen kompakten Überblick über aktuelle Themen und Trends der Informationstechnik zu geben. Sie wurden von Masterstudierenden der Wirtschaftsinformatik der Fachhochschule Dortmund im Rahmen einer Semesterbegleitleistung im Masterkurs "Informationswirtschaft" verfasst. Jeder Beitrag behandelt ein spezielles Thema, in das zuerst allgemein eingeführt wird. Anschließend wird es mit seinen verschiedenen Facetten, d.h. mit Anwendungsbeispielen, Chancen und Risiken oder auch Vor- und Nachteilen möglichst umfassend dargestellt. Den Abschluss der Beiträge bilden fast immer ein Fazit und ein Ausblick, die für die Leser richtungsweisend sein sollen.

Bachelor Thesis from the year 2018 in the subject Economics - Finance, grade: 1,7, University of Applied Sciences Essen, language: English, abstract: The progress of change in society through digitization, globalization and the rapid development of technology prompts new and innovative opportunities for companies across the world. Over the past few years, nearly everything is based on smart devices that are able to communicate among themselves. As a result, new technologies have arisen, been published and are able to be used by people around the world. One of the recently released and most popular topics is blockchain. This term earned its attention through its innovative and unpresented form of technology and has motivated several parties to learn more about this issue, examine it more closely and develop it further. Particularly the range of potential applicability makes it interesting for companies to analyse possibilities for implementation with respect to their own business. In addition, blockchain is related to another term that has arisen along with this technology, namely cryptocurrency. Especially Bitcoin is the forefather in the world of digital currencies. Over the past few years, Bitcoin has skyrocketed in popularity and value since its founding in 2009. Consequently, this digital currency has gained the attention of many people who are trying to predict the commercial development and future per- formance in the world’s economy. There are many pros and cons and some powerful businessmen have published their own opinions based upon the respective commercial interests. ...
