基于ORACLE的渤海工程地质数据库结构的分析和设计

Analysis and Design of ORACLE-based Engineering Gelogy Database Structure for the Bohai Sea

从需求分析、概念结构设计、逻辑结构设计、物理结构设计以及安全性设计等几个方面,详细阐述了基于O-RACLE的渤海工程地质数据库结构的设计方案。在分析过程中,采用面向对象的标准建模语言UML对数据库的概念结构进行建模,利用面向对象的关系数据库ORACLE提供的强大的数据管理功能对数据的存储空间和安全性能进行分析和设计,使该数据库能够提供快速、高效的数据存储、维护和检索功能,满足渤海油田示范区信息系统的应用需求。

In this paper, the design plan of ORACLEbased engineering geology database structure for the Bohai Sea is described with respect to demand analysis, conceptional structure design, logical structure design, physical structure design and security design. In the analysis process, the objectoriented unified modeling language (UML) was used to model the conceptional structure of database, and the objectoriented relational database ORACLE was used to analyse and design the storage space and security performance of data so that the database can provide rapid and efficient functions for data storage, maintenance and retrieval to meet the application requirements of the Bohai oil field demonstration zone information system.
