Ⅲ. FOUNDATION LAYER DESIGN
Fig. 2 shows the overall plan of the foundation layer. The basic layer is physical infrastructure of the entire logistics information platform. It is the lowest layer which composed of network infrastructure, hardware platforms, software platform and communication technologies.
Technical standards layer is the collection of regulations, agreements, norms and technical standards. It safeguards the legitimate operation of the platform.
The supporting system layer directly serves to the application layer as the first floor. It includes data acquisition, storage, transmission, processing technology, security technology, network technology, etc.. It is the fundamental of the function mold of the application layer.
Upon these supporting techniques are value-added technologies, including logistics technique, GPS, GIS, DSS, RFDI, 3D, EDI, systems integration technique, information integration of heterogeneous systems such as middleware technology, etc.. They play a great role of supporting the application layer.
Database layer is related directly to the design of application-layer services, with which the entire system can run smoothly and complete expectant functions.
