Visualizing Database for Better User Interaction - Using data visualization approach to visualize Volvo Common Logging and MISP database

Abstract

Over the last decade, as the amount of information has exploded, data visualization has been used as one of the most important presentations for displaying information in an easy to understand way. From the traditional approaches like tables and bar charts to modern approach that a lot of graphics are used, the development of data visualization reflects the changing requirements that people perceive data. Nowadays, graphics are used widely in data visualization and the presentation of data is more elegant and descriptive than before. This thesis work completed at the Integration team at Volvo Information Technology aims at visualizing complex database in graphics, and users who work with the database can view the connections between components clearly from the interfaces and benefit by its user-centered interactions and graphical presentations. The current practices were analyzed, and the theories and methods were studied. The thesis work started with finding out stakeholders’ requirements, followed by several designing iterations. During the process stakeholders actively participated in providing fruitful suggestions and helped to test the prototypes for better revisions. One project has been deployed successfully in the production, while the other is still in progress. Future work is needed, but the concept of the thesis work has been handed over to the team for later implementation.
