Abstract

The emerging trend of using Business Intelligence (BI)-Applications in public organizations to support the decision makers belongs to the backend oriented e-government activities. A prerequisite for BI is data integration, which is still an expensive task. At the same time, public organizations are forced to save money, due to shrinking budgets. As cloud computing is marketed as key technology to gain higher efficiency and generate cost savings, we analyze in this paper its possible impact on data integration in the public sector. We describe first the conventional approaches of virtual and materialized data integration. Using technical and E-government specific criteria, the advantages and disadvantages of the two different approaches are shown. Afterwards, the paper scrutinizes the suitability of virtual and materialized data integration in the cloud by proposing and analyzing technical architectures that implement the two different methods. These architectural propositions are then discussed applying the criteria from the precedent chapter. Finally, we summarize our results and explain how we want to proceed with our further research.
