Statistics evaluation for Teleacademy.it

Teleacademy's statistics evaluation tool, developed by Amatulli Luca, Mair Paul, and Martin Johannes, offers users the ability to select and display data from a PostgreSQL database or files. It provides visualizations in three formats: line graphs, bar graphs, and pie graphs. The tool integrates advanced programming techniques, such as polymorphism for runtime SQL query selection and RTTI for dynamic graph resizing, ensuring a user-friendly experience. It supports various user stories with dedicated CRC cards for GUI, data collection, SQL connections, and graph generation.
