The system is designed as a desktop application for small and medium business owners who can make complex management decisions based on the information received. The application is suitable for laboratories, hotels, stores selling food and household goods, various types of orders and services related to food products etc. For its creation, a programming language was used – Python, a relational database – PostgreSQL, for the GUI implementation– Tkinter and for version control – Git and GitHub. In the implementation we have adhered to all good programming practices. The detailed description of the program code aims to demonstrate its efficiency, functionality, simplicity, flexibility and adaptability. Creating the database and the relationships between the objects demonstrate the program integrity, security and normalisation of the data.
