Over a three-month period, Marcel Simma developed and expanded a suite of learning and simulation modules in the marcelsimma/appdev24 repository, focusing on C#, SQL, and object-oriented programming. He delivered features such as a Tic-Tac-Toe game, a calendar, and a comprehensive zoo management simulation with persistent MySQL integration. Marcel applied class design, refactoring, and data modeling to create maintainable, extensible code, introducing systems for animal feeding, caretaker assignment, and cost calculation. His work emphasized robust backend development and console application design, resulting in a scalable, data-driven foundation that improved onboarding, maintainability, and operational visibility for educational applications.

Dec 1, 2024December 2024 Monthly Summary for marcelsimma/appdev24: Delivered an end-to-end zoo management simulation with a persistent data layer and improved observability. Implemented the core Zoo management architecture (Gehege and Zoo classes) with Start-based initialization and updated SQL queries, establishing a reliable startup flow. Introduced a comprehensive feeding domain (Futter, Tier) with per-animal and enclosure feeding management and cost calculations, plus enriched Zoo output to show enclosure names, animals, and related feeding data. Added caretaker management (Pfleger) to assign caregivers to enclosures and display assignments. Established a MySQL-backed database integration to create and structure tables for zoos, keepers, enclosures, animals, and food, including population scaffolding. These changes collectively create a scalable, data-driven foundation for operations and analytics, enabling faster iteration and clearer cost/feeding visibility.

Oct 1, 2024October 2024 performance summary for marcelsimma/appdev24: Delivered expanded Learning Exercises by introducing several new C# programs for weekly assignments (array manipulation, string searching, and a Tic-Tac-Toe game). The codebase was refactored to improve type handling and added new capabilities for counting characters and managing absence lists, expanding the scope and robustness of the learning modules. This work increases learner engagement, shortens onboarding time, and enhances maintainability and scalability of the application. Commit abca86ce576efa6411200a4249fa5c64786c54f7 was applied to implement the update.
