【正文】 duction of the same products enterprises innumerable, enterprises want to win in the petition, they must constantly bring forth the new through the old, to lower the cost of changing rapidly to meet consumer demand, which requires quick response logistics system. To quickly response, information feedback must be timely, which requires enterprises to set up their own logistics information system.Development: the petition among modern enterprises is the petition between the supply chain to a great extent, but in the whole supply chain, there are lots of links, information is relatively plex, it is much more difficult to municate between enterprises. Links to free munication, to achieve information sharing, supply chain logistics information system is imperative.Technology trends: the rapid development of puter technology, a wide extension of the network, so that the whole society has entered the era of information.In the age of the Internet, only in the information society, enterprise will have greater development. Moreover, the development of information technology has been developed for the information system to lay a solid foundation. As a member of society, logistics as a social service industry, must establish the information system of logistics industry in their own.Logistics information system is the nerve center of the logistics system, as the entire logistics system of mand and control system, can be divided into a plurality of seed system or a variety of basic functions. Usually, its basic functions can be summarized as the following aspects:Data collection: logistics data collection is the first data through the collection subsystem from internal or external collection to the pretreatment system, and finishing as the format and the form of system requirements, and then through the input subsystem is input to the logistics information system. This process is the premise and foundation of the play role of other functions, if one started to collect and input information is inplete or incorrect, be in next in the process of the result may be the actual situation pletely at odds, this will lead to serious consequences. Therefore, in a measure of information system performance, it should be noted that the collection of data integrity, accuracy, and capability of checking and preventing and resisting destruction ability.Information storage: logistics data through the collection and input stage, before processing the, must be stored in the system down. Even after processing, if the information and use value, also want to save it for later use. Storage function of logistics information system is to ensure that the logistics information has been lost, can not not aliasing, do not leak, sorting properly, readily available. No matter what kind of logistics information system, in relation to information storage problems, should take into account the amount of storage, information format, storage, use, storage time, security and other issues. If these problems are not solved properly, the
