    Design and realization of document database of Three Gorges Project sediment information system
    三峡工程泥沙信息系统文档数据库的设计与实现
短句来源
    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 multiusers C/S system shows the data integrity,data security,data concurrency and system stability can basically meet the requirement brought forward by users.
    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。

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。

A document database was designed for maintenance of and inquiry into large amounts of nonstructural sediment data at the Three Gorges Project. First, an entity-relationship model was developed based on a supply-demand analysis, and then converted to a relational model supported by DBMS on the platform of Oracle. During the process of program development, the joint between the core objects ADO2.6 in Visual Basic and Oracle8i made it possible for users to maintain and inquire into document information in the Oracle...

A document database was designed for maintenance of and inquiry into large amounts of nonstructural sediment data at the Three Gorges Project. First, an entity-relationship model was developed based on a supply-demand analysis, and then converted to a relational model supported by DBMS on the platform of Oracle. During the process of program development, the joint between the core objects ADO2.6 in Visual Basic and Oracle8i made it possible for users to maintain and inquire into document information in the Oracle database through friendly program interfaces. A final test of multi-users' C/S system shows that the integrity, security, and concurrency of data and the stability of the system can basically meet the users' requirements.

针对三峡工程泥沙科学和技术的大量资料和文献非结构化特征 ,设计文档数据库来维护和查询这些数据 .首先根据需求分析建立了实体关系模型 ,再将其转化成在Oracle环境下DBMS支持的关系模型 .在文档数据库前端应用程序开发过程中 ,运用了VB数据库最核心的对象群ADO2 6与Oracle8i对接 ,实现了用户通过友好的应用程序界面对Oracle数据库中各类文档资料的维护和查询 .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地满足用户提出的要求 .
