Then , we master the requirement of the enterprise for the system in function and information . we protract the data flow picture of the system and write out the data dictionary 通过归纳、整理,掌握了用户对分系统的功能需求、信息需求与基本使用要求,绘制出电泵物资管理系统数据流图,撰写了电泵物资管理分系统的数据字典。
You will save some work by reference to material in the target format s documentation or data dictionaries , but if anything , you should take more care in formalizing the semantics of your modifications and extensions 参考目标格式文档或者数据词典中的资料可以省不少力,但是如果有什么变化的话,则需要更加注意形式化所作修改和扩展的语义。
The needs of a real hydraulic engineering are discussed in the thesis , and the data dictionary is suplied for developing and software maintenance . the software interface units is also introduced , such as menus and windows 文中讨论了一个水利工程对应用软件的实际需求,并提供了用于开发和维护系统的数据字典,对于系统的诸如菜单和窗口等用户界面单元也加以介绍。
The information is summed up from every function departments in the company . the operation flow and the top data flow picture are drawed by coordinating the information . the data dictionary is gived according to the data flow picture 该系统将分散在各个职能部门的信息,通过归纳、整理,绘制出投标报价系统的业务流程和分系统一级数据流图,并对应数据流图给出了数据字典。
Based on foxpro , generation technology is obtained to ensure the system to be of maintainability , application and flexibility . the system includes a complete naming system , writing regulation for generation program , the detail definition mothed for data dictionary , application scope and basic operation . the data retrieving model with chinese characteristics and extensive flexibility is also given 最后,建立了以数据字典为核心的mis开发环境,以保证系统的可维护性、适应性和灵活性并给出了基于foxpro的生成技术,包括完整的命名约定、生成程序的书写规范、数据字典的具体定义方式和应用范围及基本操作,给出了具有中文特点和广泛灵活性的数据检索模式。
The data and the function requirements for this database system are deducted firstly by the analyzing of the data flow fig and the compiling of the data dictionary . then , the local e - r fig and the whole e - r fig are obtained by concept structure design . the database physical design is finally completed by sql server 2000 and the whole structure of the database is built 首先通过分析系统数据流图,编写数据字典,得出数据库系统的数据和功能需求;然后经过概念结构设计得到数据库局部e ? r图和全局e - r图,经过逻辑结构设计将e ? r图转换成关系数据模型;最后采用sqlserver2000作为工具完成了数据库的物理设计并建立了数据库的全部结构。
In section b , the author treatises the course of the construction on the information system consisting of general target , analysis of demand , design on fuction , data flow , design on software and hardware , math model and arithmetic design , data form and data structure , data dictionary , interface design and module design etc . in section c , the system is tested as an example of jiangyin and some harvest is obtained 第二部分,笔者对农用地定级估价信息系统的建设进行了详细的论述,包括系统的总体目标、需求分析、功能设计、数据流程、软硬件环境设计、主要数学模型与算法设计、数据组织与数据结构、数据字典、用户界面设计、模块设计等。第三部分,笔者以江阴市为例对系统进行了测试,获得了一定的成果。
