中国海洋油气田工程数据管理系统的数据分析建模及其实现

Data Analysis and Model and Actualization ofEngineering Database and Management SystemFor China Offshore Oil-Gas Fields

本文介绍一个面向海洋油气田开发概念设计的工程数据管理系统.首先分析了海洋油气田开发概念设计数据的特点,得到了数据的概念模型.然后提出了描述专业内数据结构的层次模型,并采用宏观层次模型和微观关系模型相结合的方式描述全部数据结构。分析了数据的组织形式和关系数据库的范式,设计了数据库结构和数据的存取路径。最后,应用先进的面向对象程序设计方法,采用事件驱动方式控制程序流程,实现了结构简洁、便于维护的应用数据库管理功能模块。该数据库的建立为进一步开发海洋油气田概念设计智能化系统奠定了基础。

An engineering database and management system scheme design of offshore oil exploitation. First the data of scheme design of offshore oil exploitation is analyzed and the dada's concept model is obtained. Then a hierarchy model is constructed to describe the data structures in specialities. And this macroscopical hierarchy model combines with the microcosmic relation model to describe overall data structures. The organization of data and normalization of database are analyzed. The database structures and data in and data out paths are designed. At last by employing advanced object ?oriented programming method and event ?driven method to control program's flow, a database management system is actualized which has a simple structure and easy maintenance. This database provides basis for intelligent scheme design system for offshore oil exploitation.
