摘要
介绍了南阳农业灌溉远程工程分析及管理决策系统设计及其数据库的预建。系统利用Internet,采用编程语言ASP与管理数据库SQLServer2000,使用一些特别的对象集合如ActiveDataObject(ADO)来进行连接;数据库预建从系统设计出发,在设计方法上按软件工程学的软件设计基本方法———原型化设计方法,在充分考虑三级模式结构的基础上,通过需求分析,概念设计,逻辑结构设计,物理结构设计,对数据库进行标准化设计。
The project analytic and management decision-making system of Nanyang agricultural irrigation of long distance and the pre-structure of its database are introduced. By making use of Internet in the system, programming language ASP, management database SQL and Server 2000, some particular objects are used to make connections. The pre-structure of the database is based on the system design. The principal method of software design-prototype design method is used in the design process. On the basis of the model structure of 3 levels, the standardized design of the database can be achieved by making analysis of the demand, logical design, physical structure design.
