Implementation Of Distributed Document System Based On Project Flow

With the rapid development of information technology, e-government has more and more importance by the government department, environmental protection system because of its special properties, however, does not have a high level of electronic and environmental reporting mostly stay in the paper, project management is not timely, not only is more tedious, and to plan as a whole to consider the superimposed effect of regional environmental protection project has brought great difficulties, it is difficult to research project group are analyzed from the macroscopic Angle, this article based on the actual environmental information platform project, combining with the characteristics of Erhai Lake basin environmental protection project group, this paper proposes a distributed document system based on project process.This paper proposes a distributed document management system based on project process, using the Web and FTP service, discard the separate Web pattern of overload and separate FTP mode control difficulties such as faults, using distributed technology, in XML, which is the core of the system data interaction, improve the efficiency of network transmission, using the local cache technology to solve the problem of multimedia, the interaction between the big data, at the same time, in Erhai Lake protection program, for example, was designed and implemented based on the technology of distributed document of the project process.First of all, this paper introduces the domestic and international document system, distributed systems, project and project group of research present situation, put forward a distributed document system based on project process, then the second chapter describes the theory and building systems technology, mainly including distributed technology, XML technology, project process and project group, etc. The third and fourth chapter with the consideration of the characteristics of Erhai Lake basin environmental protection project of design to realize distributed document system based on project process, using JSP+MySQL+Flash+software architecture such as XML+HTML5+.NET, in accordance with the requirement analysis, system architecture design, detailed design realization about the design of the distributed document system step by step implementation process.Secondly, the key technologies of the system in the fifth chapter to do detailed research, mainly includes information extraction system internal information communication protocol, the photos were, map location algorithm, FTP file breakpoint continuingly, key technology such as information security said, according to the extraction of information, transmission and label order to study the key technology.Finally, the distributed document system proposed in this paper for overall performance test, the system in the aspect of information processing, transmission, said all achieve the specified requirements, has been successfully applied to seek environmental protection system, is the national environmental protection system in the promotion.
