Design, development and test of a graphical user interface for visualizing data quality measurements on Italian Open Government Data

Today with the development of the Internet, data is used in more and more places, such as training the model and data analysis for businesses and governments to improve their services or gain benefits. With more and more data, it is difficult for people to monitor the quality and accuracy of all data. Poor quality data can lead to some negative results. The aim of the thesis is to design and develop a web-application to do data quality analysis based on a generalized algorithm provided by Davide Vitaletti, and display the analysis results visually for users. The application includes back-end and front-end. The back-end is developed based on the web framework, Flask and ORM framework, SQLAlchemy. The front-end is developed based on the framework, Vue. Vue is an easy to learn and for rapid development framework. Based on the different account role, the users have different permissions. The main modules of the application include account management, file management, analysis setup, analysis result. Its main function is to analysis the data on Italian Open Government Data for users to visualize data quality measurements including Com-I-1 DevA, Com-I-5, Acc-I-4, Con-I-3, Con-I-2 DevB and Con-I-4 DevC. Thesis quality measurements are defined in ISO/IEC 25024:2015.
