Andrea Luescher focused on improving data quality within the sogis/gretljobs repository by addressing a recurring typo in drainage material names across SQL scripts and views. Using SQL and database development skills, Andrea standardized the spelling of 'Kunststoff' in key datasets and reporting views, such as alw_drainagen and vsadssmini_wk_mangel_leitung. This targeted bug fix enhanced the accuracy of material categorization, reducing misclassifications and supporting more reliable analytics. The work was delivered through three well-documented, low-risk commits, demonstrating careful version control and traceability. Andrea’s approach improved data consistency and supported better business decision-making based on drainage material information.
