| Great loading point is the modern railway loading place in the new period which is based on the intelligent loading system, capacious storage ability and the efficient operation. It can realize the centralized storage, the integral distribution of the train, entire loading and departure, so it has significance to the National railway and the producing efficiency. It is necessary to build up the information system to adapt the modern logistics. To build up the information system does not only guarantee the operation of the work, but also becomes the extension of the railway information system towards the whole society. How to build up the efficient and stable information integration with the present information system is of momentous current significance towards the modern logistics.Nowadays, there are two types of techniques on information integration. They are data warehouse method and mediator. With data warehouse method, the data is picked up and transferred as requested and is stored in the data warehouse. The users’inquiry is the inquiry on the data in the warehouse. As for the method of mediator, data is not stored together. The users are provided with a virtual data view. The wrapper wraps the data source. The users’ inquiry is performed by various information sources after being analyzed and transferred. The data of the various information sources is integrated and filtrated before it is given to the users.In this thesis, firstly, it analyses the current condition of the development railway information system and the technique of the information integration. Then, it analyses the demand of diversified logistics managed system, and the request of information integration in the railway manage production. At last, based on the update information integration technique and demand of diversified logistics managed system, the thesis compares the two methods and recommends the mediator to be the best choice. |
