In my bachelor thesis with the title "Development of a User Interface for an ERP-System" I developed a prototype in the language Java. The programming exclusively happened in an editor and without any GUI builder. All icons and symbols were designed by myself. The essential gui's characteristics are the navigation tree which can be faded in and out, the possibility to represent two transactions next to each other as well as the extensive filter and search functions within tables. The demo video shows the general structure and cycle of the user interface. All visible data and information is fictional.
