Dynamic Web Technology Research

Rapid development of computer technology and network technology provides dependable guarantee for building high quality Enterprise Information Management System (EMIS) system.Oilfield Information Management System has developed too much under the large need of network applications. Under the basis of databases, these units also had developed some applications. But those applications have certain drawbacks, for example. They are basically running under the mode of C/S and the operation and maintain are not too convenient. These drawbacks have resulted in the rather difficulties for popularization.Addtionally, the whole oilfield management information system is lack of uniform, highly efficient, safe and reliable production information system. Dynamic Web technology has applied to EIMS, which raises work efficiency and reduces payout cost hugely.Based on such considerations, we bring forward the project of developing this oilfield production information system with an example of the Down-Holl Service Department of Jianghan Oil Field. This essay discusses the problems from hereinafter four aspects.1. This chapter introduces the character, architecture and function of enterprise information management system (EIMS) and point out status of EIMS in china. It also shows the development of the architecture of EIMS in China.With the development of enterprise application, the enterprise application structure is changed into muti-tier distributed structureAdopting muti-tier distributed structure can raise the extensibility and adaptability of the enterprise. From the discuss we can conclude that building a n-tier distributed architecture is the best way to develop enterprise information system in China.2. This chapter introduces the concept and structure of J2EE framework which include four tier structures: client tier, web tier, business tier and enterprise information system tier. It explains the relations among these four tiers. It emphasizes the core component of J2EE—EJB and explains how to use EJB. At the end of this chapter it discuses the advantage of J2EE structure.3. Enterprise Information Management System of the Down-Holl ServiceDepartment of Jianghan Oil Field includes two parts: production management system and special vehicle controlment system.This chapter introduces the production management system in the Down-Holl Service Department of Jianghan Oil Field. The production management system includes three modules: document release, production controlment, data- gathering. Data backup mechanism is explained at the end of the chapter. Document release module is used to release and maintain message and bulletin moreover it supplies an information communication platform. Production controlment is used to collect unit's data and build production journal. Data gathering modul can collect other unit's data and put them into center database server, which supplies a convenience for querying and operating.4. This chapter introduces the special vehicle controlment system and analyses the system requirements, database design and system implement. The accomplishment of the system gives a huge convenience for managing and maintaining special vehicle. At last I summarize the thesis and imply some problem needed to research andexplore in the future.
