【摘要】：為實現(xiàn)對航運集裝箱作業(yè)全過程的追蹤管理，各航運公司紛紛建立起航運集裝箱物流信息管理系統(tǒng)，形成對集裝箱物流業(yè)務(wù)的科學(xué)化、信息化管理。由于海內(nèi)外相互獨立的信息系統(tǒng)，具有地域分布性和數(shù)據(jù)的異構(gòu)性，，從而導(dǎo)致了“信息孤島”現(xiàn)象的產(chǎn)生。因此，為了便于及時獲取海外集裝箱狀態(tài)信息和各種費用信息，就要求與海外港口的信息資源進行交互，保持國內(nèi)外集裝箱信息的同步。 本文首先深入探討了多種異構(gòu)數(shù)據(jù)庫動態(tài)捕捉策略與技術(shù)的原理、應(yīng)用條件及各自的優(yōu)缺點；并詳細闡述了數(shù)據(jù)轉(zhuǎn)換、數(shù)據(jù)更新、沖突檢測與解決的相關(guān)技術(shù)和方法。其次，結(jié)合本航運集裝箱管理信息系統(tǒng)，提出了適合本系統(tǒng)的同步策略。此策略應(yīng)用改進的控制表變化法來捕獲變化數(shù)據(jù)，利用XML數(shù)據(jù)格式作為數(shù)據(jù)轉(zhuǎn)換的中間數(shù)據(jù)模式，采用關(guān)鍵狀態(tài)同步的方式，對集裝箱信息的進行同步。最后，本文對集裝箱物流的業(yè)務(wù)需求和操作流程進行了分析，結(jié)合本系統(tǒng)的功能，介紹了控制表的設(shè)計和應(yīng)用，并詳細闡述了本集裝箱物流管理信息系統(tǒng)各功能模塊的作用。 本文提出的數(shù)據(jù)同步策略能夠較好地應(yīng)用在集裝箱物流信息系統(tǒng)上。改進的控制表法能夠及時地獲取源表數(shù)據(jù)的全部變化序列，以便同步過程能夠獲取完善的控制信息。關(guān)鍵狀態(tài)同步的方式可以有效地降低同步數(shù)據(jù)的傳輸量，提高本地的自治性。
[Abstract]:In order to track and manage the whole process of shipping container operation, shipping companies have established shipping container logistics information management system, forming a scientific container logistics business. Information management. Because of the independent information system at home and abroad, with geographical distribution and data heterogeneity, resulting in the phenomenon of "information island". In order to obtain overseas container status information and various cost information in time, it is necessary to interact with the information resources of overseas ports and maintain the synchronization of container information at home and abroad. In this paper, the principles, application conditions, advantages and disadvantages of dynamic capture strategies and techniques for heterogeneous databases are discussed. And elaborated the data conversion, the data update, the conflict detection and the solution correlation technology and the method. Secondly, unifies this shipping container management information system. A synchronization strategy suitable for the system is proposed, which uses the improved control table change method to capture the change data, and uses the XML data format as the intermediate data mode for data conversion. The key state synchronization method is used to synchronize the container information. Finally, this paper analyzes the business requirements and operation process of container logistics, combined with the functions of the system. The design and application of the control table are introduced, and the function of each function module of the container logistics management information system is expounded in detail. The data synchronization strategy proposed in this paper can be applied to container logistics information system, and the improved control table method can get all the change sequences of the source table data in time. In order to obtain perfect control information, the key state synchronization can effectively reduce the amount of synchronous data transmission and improve local autonomy.
