Design and Implementation of Traceability Management System for Pigs Based on Personal Digital Assistant

摘要

The traceability management system for pigs based on personal digital assistant (PDA) was constructed by software engineering method to provide the traceability management for pork safety. This traceability system included information managements for pig breeding and pig quarantine inspection supervision. It also realized the record and supervision of pig information, feed usage, veterinary drug usage and quarantine inspection. We mainly introduced the designs of systemic structure and functional structure of the traceability system and key techniques of system implementation.
