Analysis And Design Research On E-Government Of Harbor And Shipping

With rapid development of the global economy and information technology represented by multimedia computer and internet, people's life style and thinking mode have many great changes. It also has profound influences on people's life and work. The phenomena demands governments to open and modernize undoubtedly.The management of harbor and shipping is a necessary part during the development of local transportation. It has characteristics of both governing and enterprise. Because the administrative department should not only cany out polices, laws and regulations drafted by government, but also should be responsible for a healthy hydraulic market.Introducing E-government to management of harbor and shipping can improve present situation of management and work efficiency greatly. It also strengthens the scientific decision making ability of administrative management. Therefore it's an important method to improve and perfect harbor and shipping service, and an effective approach to promote the communication between administrative department and society.For a long time, although some administrative departments obtain several achievements, there are many weaknesses. The whole construction is lack of management, targets and plans. The system structure is analysed unreasonably and its security is poor. A lot of harbor and shipping E-government constructions, which are invested with enormous finance, are repudiated and implemented again. It is an important factor which restricts the management of China harbor and shipping to connect with international practice, and affects our harbor development seriously as well.Firstly, the paper brings analytic method based on information flow into analysis of PMB information structure, using a practical project of Liaoning province. Based on that, reasonable system structure and function frame are established, offering design proposal of system function module. Secondly, this paper introduces UML and finishes mapping the model to Struts package, providing method and foundation to programming. Finally, according to system security principal, the paper presents a design proposal based on Hash and RSA algorithm, establishing basis of design and realization of digital signature.
