    När tekniken behöver hinna ikapp affärsbehoven: En studie med fokus på hur data virtualization kan komplettera ett data warehouse2019Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Data warehouse has for a long time been, and still is, an important asset for organizations to store data for analysis. In the last decade, an exponential increase in data has taken place, giving organizations increasingly greater opportunities to make data-driven decisions in completely new ways. Nevertheless, in many cases, it also puts pressure on organizations to use data as an asset to react and take advantage of opportunities in a harder business climate, or even to maintain competitiveness. In order to enable organizations to be able to react in time, flexibility requirements are imposed on the techniques used to handle data for analysis. The traditional best practices for data warehouse is predicted to soon be out of date. Organizations need to find new ways to quickly change and adapt to the needs of the market. Many organizations currently have a traditional data warehouse, and this study examines how well data virtualization can help increase flexibility by being added as a complement. This is examined through the question:How can data virtualization complement and improve a traditional data warehouse?To answer this question, a literature analysis, and a case study followed by an implementation is carried out, in which the data collection consists primarily of tests performed on the implementation result, observations and interviews.The result shows a divided picture, where performed tests can potentially be seen as questioning parts of the interview results and existing literature. Based on the result, some findings can be made about in which use-cases data virtualization does not fit, and gives a picture of when it can be an alternative. Data virtualization should be seen as an extension of a data warehouse that enables the federation, transformation and computation of data, where data structures can be changed at any time. However, an organization that embraces this more flexible solution must be prepared for substantially increased response times in data extraction.
