This repository contains the full development of an information system designed for the needs of the company JB Modelarija Blažeka d.o.o. as part of the university course Information System Development (PIS) at the Faculty of Organization and Informatics, University of Zagreb.
The system models real business processes related to procurement, finance, and production, and demonstrates the application of system analysis and design techniques including process modeling, data modeling, and implementation via Oracle APEX.
The project was conducted in a team of three students with the objective of analyzing, modeling, and implementing an information system that reflects the operational workflows of a real-world manufacturing company. The system focuses on:
- Procurement process: Managing suppliers and incoming orders
- Production monitoring: Employees, production tracking, material usage
- Finance overview: Cost allocation and tracking (model-level)
