Research And Demonstration Of The Heterogeneous Data Exchange Method On The Comprehensive Logistics Information Platform

Because of the Comprehensive Logistics Information Platform didn’t provide external data interface, the logistics data which generated from trading process on the platform couldn’t be transferred to the enterprise information management platform or other e-government platform, which led to that it was unable to reuse the data and couldn’t reach the requirements of data collaboration and data sharing. The article put forward a heterogeneous data exchange method based on the XML technology, which fulfilled the batch extraction, conversion and safety relay according to the data requirements of the service object, achieved the connection of the Comprehensive Logistics Information Platform and the other enterprise platform, and increased the service efficiency of the data.The first, based on the demand for data exchange between Comprehensive Logistics Information Platform and the service object, the article analyzed the features of the structure, function and data storage of the Comprehensive Logistics Information Platform, studied the characteristics of data types and format requirements of the service object and the complexity and the frequency of data exchange, knowing the requirements of receiving data from logistics business, especially customs declaration, put forward the research of the heterogeneous data exchange method and the design idea of data exchange system.Secondly, the article studied the different kinds of heterogeneous data exchange method, and drew a conclusion that the data exchange method based on the XML technology was the best to match the need of data exchange between the Comprehensive Logistics Information Platform and other heterogeneous systems. Proposing the heterogeneous data exchange process and used the data transformation method based on XML and data transfer method based on HTTPS to solve the data conversion and security transmission.Thirdly, according to study the data extraction technology, the article designed the process of data extraction, and used the multithreading technology to solve the problem that the server response slow and page buffer a long time caused by parsing the page.Fourthly, according to the heterogeneous data exchange process and the data extraction technology, the article took extracting customs declaration logistics data as examples to study the build the data extraction model, providing theoretical basis of data presentation for developing the heterogeneous data exchange system.Fifthly, based on the customs declaration business trading system of the Comprehensive Logistics Information Platform, the article used.Net development stack to develop the heterogeneous data exchange system according to the data exchange process and the data extraction model which studied before, realizing the extraction, conversion and transmission process of customs clearance logistics data. The last, the paper used the Comprehensive Logistics Information Platform to carry out empirical study on the heterogeneous data exchange method researched before.
