the requirements for food quality traceability system, and determined its function module. Using unified modeling language
(UML), the system’s business process, static model and dynamic model are visualized. The system model is designed
by means of use case diagram, sequence diagram and class diagram; at the same time, the related business processes are
described by activity diagram.

Key words: food, quality traceability, unified modeling language, system analysis
