摘要
在三峡工程泥沙问题上,为了给科研工作者和决策者提供多层次、多方位的信息,增强其在泥沙信息与决策过程中的分析、综合和判断能力,建立一个以查询和更新为基本功能的数据库系统是很有必要的。对三峡工程泥沙信息系统中文档数据库关系模型的建立和具体的实现过程作了较为详尽的叙述:在其前端应用程序开发过程中,运用VB数据库最核心的对象群ADO2.6实现了与Oracle8i对接,并在多用户C/S系统中测试表明,数据的完整性、安全性、并发性和整个系统的稳定性都能够较好的满足用户提出的要求。
On the issue of Three Gorges project, in order to provide information from multilayer and different angle for scientific researchers and decision makers, as well as to improve the ability of analyzing,synthesizing and judgment during the process of decision, it is necessary to establish a database system with basic function of query and update. In this article, it is narrated in details about the design and actualization of document database's relational model in Three Gorges Sediment Information System. During the process of application program development, we realize the joint between the core objects ado2.6 in Visual Basic and oracle8i. The final test in multiusers C/S system shows the data integrity,data security,data concurrency and system stability can basically meet the requirement brought forward by users.
