【摘要】：为实现对航运集装箱作业全过程的追踪管理，各航运公司纷纷建立起航运集装箱物流信息管理系统，形成对集装箱物流业务的科学化、信息化管理。由于海内外相互独立的信息系统，具有地域分布性和数据的异构性，，从而导致了“信息孤岛”现象的产生。因此，为了便于及时获取海外集装箱状态信息和各种费用信息，就要求与海外港口的信息资源进行交互，保持国内外集装箱信息的同步。本文首先深入探讨了多种异构数据库动态捕捉策略与技术的原理、应用条件及各自的优缺点；并详细阐述了数据转换、数据更新、冲突检测与解决的相关技术和方法。其次，结合本航运集装箱管理信息系统，提出了适合本系统的同步策略。此策略应用改进的控制表变化法来捕获变化数据，利用XML数据格式作为数据转换的中间数据模式，采用关键状态同步的方式，对集装箱信息的进行同步。最后，本文对集装箱物流的业务需求和操作流程进行了分析，结合本系统的功能，介绍了控制表的设计和应用，并详细阐述了本集装箱物流管理信息系统各功能模块的作用。本文提出的数据同步策略能够较好地应用在集装箱物流信息系统上。改进的控制表法能够及时地获取源表数据的全部变化序列，以便同步过程能够获取完善的控制信息。关键状态同步的方式可以有效地降低同步数据的传输量，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.
