The Design And Implementation Of Mobile Data Terminal In Logistics System

The development of Electric Business requests more powerful basicestablishment to build new logistics deploying-delivering center gathering withinfOrmation floW commodity floW capital flow and logistic. Using OO concept andaccording to peculiarity of embedded system, the paPer analyzes and designs mobi1edata terminal in logistics system with UML modeling tools.The paPer focuses on three aspects below:1. Make some discussions of Electric Business composed of fOur flows above.According to characteristics of mobile POS machine applied in logisticsmanagement system, the paper discusses how to analyze and design it withOO concept.2. Aiming at two types of mode to manage software and hardware of .embeddedsystem, aPplication of logistics system is realized. One is design of regiebased on a ripe embedded OS just like Palm OS. For the consideration ofefficiency and simpleness, the other is application of visit-sale system withprofessional embedded system, which manages software and hardware withAPI functions3. As to OO programming language, we have realized system above easily andlink OOA&OOD with OOP seamlessly. But to some language not accordingwith OO, we use some methods to simulate OO progralnming language.Because of the complexity of these aspects, there are lots of theoretic andpractical research works to be developed. These researches are important to makeavailable Electric Business and development of embedded system with OO concept.
