| The information management system of engineering supervision of CNPC Huabei Oilfield Company takes use of advanced network information technology and has realized information sharing and prompt information inquiry. The information system can make the chief leaders, the department directors, the common workers and the related staff obtain information promptly. This information system provides not only a way for the staff and related staff to inquire the open information, but also more information inquiry for the department directors and chief laeaders. In addition, it provides dynamical, essential, prompt and rich information to manage and assign tasks. This greatly improve the efficiency of all kinds of tasks of the engineering supervision of CNPC.This paper analyzes the design patterns of several popular information management systems, combines the practical demand of the Engineering Supervision Department of CNPC, put forwards the design pattern of the information management system based on the system structure of Web multilayer application software, introduces the main technologies used for realizing system, including object-oriented, UML, ORACLE database, etc.After producing the system design pattern, this paper discourses system design and its realization in detail.Firstly, the paper introduces the whole design plans of the information management system of engineering supervision of CNPC including the design plans of the system function module and the system database;Secondly, taking the information management module of the integrated section office for example, the paper discourses the realization of the concrete function module.Thirdly, the paper introduces the problems met with and solved in the course of the design and realization of data exchange between isomerism databases, the optimizing and using of the database, the realization skills for the multi-conditions pulled tabulates the fuzzy inquiry singlescroll SQL sentence, etc.Finally, the paper explains the system test. |
