Research And Application Of Information Integration Techniques And Management Methods In Shipping And Maritime

According to the information characteristics and the needs to information integration and collaborative management in the shipping and maritime fields, this dissertation presents "Research and Application of Information Integration Techniques and Management Methods in Shipping and Maritime". The main contents are as follows:First, shipping and maritime system integration based on data integration. Because middleware technology has advantages to achieve resources sharing between different systems, learning from the successful use experience in other industries, this paper applies the middleware technology to the data resource integration and builds shipping and maritime data warehouse. This paper uses XML technology to realize heterogeneous data integration in the various application system databases, to provide interface and to build general data standard. XML technology has ensured data security, effectiveness and sharing, and provided a powerful guarantee for data integration of the existing and future application systems in shipping and maritime fieldsSecond, research on the key technologies of cooperative office in shipping and maritime system based on application integration. Cooperative office has become the symbol of informationization in all industries. Shipping and maritime fields are eager to realize information sharing and cooperative management within and between the related organizations. For the deficiencies of the distributed systems of Shipping and Maritime Bureau, this paper uses SSO mechanism to integrate the existing dependent business systems. On the basis of SSO mechanism, this paper uses integrated access control as the safety guarantee and uses customized workflow as the process drive to ensure the information safety and sharing and to push.information forward within all departments.Third, research on management methods in shipping and maritime fields based on data mining. Based on information integration, this paper uses data mining methods to realize deeper analysis and comprehensive understanding. For the generalization ability of a single prediction model is not high, this paper studies on the integration prediction method system and framework and uses this method to predict monthly throughput of the port cargoes and has got a good result. General association rule algorithm only generates rules on data contents. Because of lack in using domain knowledge, general association rules algorithm has generated a large number of useless underlying rules without general conclusion. Therefore, this paper presents multilevel association rules algorithm and uses domain knowledge to realize mining on different levels of association rules, especially on the higher level.Mining on data of water transportation based on SQL Server. Based on the developed project--water transportation management system, this paper uses ETL tools, OLAP tools and DM tools, from the processes of the preparation, software installation, project creation and data source establishment, to describe how to realize data integration, data analysis and data mining based on SQL Server 2008. This paper realizes the modeling and analysis, OLAP and data mining on the multi-dimensional data in water transportation of some province.Fourth, application of information integration technologies in shipping and maritime integrated platform system. Based on the development situation of shipping and maritime management, combining the requirements for informationization in this field, this paper presents the main functions, construction system and objective of Yunnan shipping and maritime integrated platform and uses J2EE three-layer framework to realize the Yunnan shipping and maritime integrated platform which regards middleware and cooperative management as the core.
