Chemical Enterprise Intranet Integration Optimizing Technique And Application

This paper analyze the necessity of building Intranet in chemical enterprise, research the character and security of Intranet, especial to two important network techniques, which are Web technique and connection technique between Web server and database. According to the practice, using the solution of Microsoft network software, which are suitable for the MIS of chemical enterprise, is used to compose the development environment of the system.. The specialty of this thesis is that use server software –Tomcat to configure server, use exploitation tool of Web application programme—JSP (Java Server Pages) to design and develop the dynamic Web pages that can support striding flat roof. Through the connection between JSP and relation Database SQL Server 2000 to realize the data dynamic updating on the pages. Use thin-client /server technique to realize "thin client"---when only installing operating system in clients, and these clients can transfer application software from server. The network technique of application software can reduce the cost of governing enterprise and maintenance Intranet. And enhance application capability, ensure security of information, exert the advantage of "thin client". At the same time, the project has the creativity, which is the basis of enterprise information management and ERP. It has important practical value.The characteristics of this paper are as following,Firstly, choose JSP to as programming technique of building dynamic web, this technique use agile and strong language Java. On the flat roof technique, JSP takes the lead in realizing operation of striding flat roof. So get rid of the chain of windows flat roof when using ASP. And JSP was exploited through the open mode of Java language; other exploitation tools, web server, and application server developer can support it.Secondly, chemical enterprise is tradition industry, with china enter WTO, chemical enterprise confront the competition of the seven seas integrating. For some meaning, this competition equate to competition of knowledge economy and information. Information building of chemical enterprise is necessary. This system combines the characteristic of chemical and Intranet. Separate the whole system to inner net and outer net. In outer net, it can go along E-business of enterprise and publicize enterprise image. In inner net, it can go along emprise inner information sharing and running application software by network. After passing validate, you can enter inner net. This design can ensure the security of inner information.Thirdly, using thin-client/server technique to realize that all application programme can be attempered, managed, supported by server. Additionally, application programme was carried out in server. In this system, the client can be very low-grade configuration. Through ICA protocol in IE, the client can transfer the application software inn the server. The final document can be saved in the client, and these documents also can be printed.Fourthly, the security of information system based on Intranet flat roof includes network security and information security. Network security includes a series network security technique that fireproofing wall is representation. Those are IP address transition technique, service deputy, dummy special network technique, system separating inner net and outer net, and so on. Information security, encrypt technique is representation, includes secret key technique, database encrypt technique, and so on.Through this system researching, build the fringe mode for the integration optimizing technique of Intranet in the chemical enterprise. At the same time, exploring the direction of information building in chemical enterprise.
