The Kangas area will form a smart city in the\nfuture, which requires implementing, among others, the data warehouse of the\narea. Before implementing the data warehouse, however, there is a need to\nknow how a smart city data warehouse can be efficiently integrated with a\ncloud infrastructure in general, which was the main research question of this\nstudy. To this end, a generalizable, theoretical framework was created that can\nbe used to answer e.g., to this question. With the help of the framework, it can\nbe interpreted that a smart city requires of a cloud infrastructure at least availability,\nautonomicity, scalability, performance, interoperability, fault tolerance,\nprivacy, and security, as well as user involvement and sustainability. The use of\nthe framework was demonstrated by choosing the most important requirements\nfor the data warehouse of the Kangas area: performance and scalability.\nOf these requirements, performance was operationalized, after which two candidates\nfor the software of the data warehouse, Stardog and Neo4j, were tested\nfor it. They were installed on a Eucalyptus cloud and a benchmark was created\nthat inserted data into and queried it from them. Neo4j performed better than\nStardog in the benchmark. Stardog and Neo4j were compared subjectively as\nwell, which brought out, among others, that Neo4j is a more mature product\nthan Stardog, but that both databases can potentially be utilized in the Kangas\nproject. Finally, the framework itself was evaluated, which revealed that it functions\nas a guiding principle quite well, although it has also some weaknesses.\nE.g., it offers no specifications.
