System for Data Stream Analysis and Visualisation

Kroz ovaj diplomski rad prikazana je izgradnja sustava za vizualizaciju i analizu toka podataka. Na početku su objašnjeni pojmovi poput toka podataka i predikcijskih modela, kako bi čitatelju bilo lakše razumjeti rad. Nakon toga, dan je opis funkcionalnih zahtjeva i obrazaca uporabe. Prezentirane su tehnologije koje su se koristile za razvoj sustava, ponajprije je riječ o programskom jeziku R, sustavima Apache Spark i Kafka. Zatim je objašnjeno kako se sustav inkrementalno gradio kako bi se dobio finalan proizvod. Dani su isječci kodova koji su popraćeni objašnjenima što koji dio radi u koristi ciljnog sustava. Na samom kraju rada dan je opis korištenja sustava, gdje se prikazao izgled sučelja sustava te izgrađene funkcionalnosti.Through this final thesis, a system for Data Stream Analysis and Visualisation was presented. In the beginning, concepts such as data stream and predictive models were explained, to make it easier for the reader to understand the thesis. After that, it is illustrated what functional requirements should the system hold with the use case descriptions. Then the technologies that would be used to develop the system are presented, primarily the programming language R, the Apache Spark, and Apache Kafka systems. It was explained how the system was incrementally built to get the final product. Chunks of code are provided with the description of what is its value in the system. At the very end of the thesis, there is a user guide on how to use the system, with screenshots showing the user interface and all the functionality the system has
