The Design of the Tracing of Aquatic Products Production Based on PDA

摘要

This paper mainly studies the key technology of aquatic product traceability system based on PDA mode, and finally designs a scheme of the system. To achieve this scheme, a B/S and C/S hybrid architecture is being built. C/S, the client side, is the aquatic product traceability system based on PDA. Its function is to fulfill the operation of information and communicate with the remote server. B/S, the server side, adopts integrated management approach of SQLServer database, knowledge base, logical application, etc. At the same time, A logic scheme under the hybrid is being designed. Through these we can trace the information related to the supply chain, which verifies the application of key technologies to achieve a retrospective, and improve system stability, fluency and latency. This paper has done a thorough and useful reference and exploration for the future application of PDA.
