| In the further, the internet of things, big data and cloud computing will become threemajor technologies of IT (Information Technology) industry, while data synchronizationtechnology in embedded mobile database is a core method in the these technologies.Embedded mobile computing technology has become a research focus in the fields ofdatabase and wireless network, and has been paid much more attention. Researchers andindustries pay much attention to the study of the embedded mobile database. Specially,logistics industries have got rapid development under the application of embedded mobiledatabase technology. However, there is a lot of shortcoming in the design of logisticsmanagement systems used at present, which are shown in data acquisition, datatransmission, data organization and data synchronization in the mobile databases.Modern logistics is a kind of service industry, in which computer management andcommunication technologies are crucial techniques. With respect to the current situation oflogistics industries, we study data synchronization technique in embedded mobile databasedesign. The focuses are on the data acquisition of the embedded mobile terminal, datatransmission and synchronization between embedded mobile terminals and servers,establishment and maintenance of server databases, so as to solve some problems, such asdate acquisition in data synchronization, complex of the equipment operation, and dataoverload, data error and data loss in data transmission, etc. Our disposal method is toachieve information anytime and anywhere by embedded portable devices, to simplifyoperation of mobile terminals with AndroilAPP, to diminish errors and to enhance thesafety and reliability of data by techniques of breakpoint resume, Cache andsynchronization.Our logistics database synchronization system is composed by three modules, that is,the hardware of the embedded mobile terminals, transmission and synchronization of data,and data processing of server database. The core component of the embedded mobileterminals consists of a CPU of Cortex-A8, GPS, network cards, keys and display screens, etc, in order to realize order form information acquisition and supervisory control online oflogistics systems. Data transmission and synchronization take3G technology as premise ofdata transmission and synchronization, internet work as supporter, cache and FIFOalgorithm as techniques, transfer data information of embedded mobile terminals toformer server. Server database take charge data maintenance and processing, realize theinstantaneity of data, and provide server of on-line inquiry. The three part supplement eachother, collectively realize data synchronization of whole logistics database, so as to meetthe needs of real-time of business management of logistics industry, gain integratedmanagement model of data flow and information flow, supply an informative platform oflogistics management, promote the management level of logistics industry. |
