A gprs device , which resembles a modem with an extended at command set , must define a context using an at command before it enters data mode Gprs设备类似于拥有扩展at命令集的调制解调器,在进入数据模式之前必须使用at命令定义一个上下文。
In system structure , the model of nodes , which afford operational object , are established . the data mode of system defines distributing of every data with object in the system in order to provide essential data support of realizing system 系统体系结构里,建立了构成整个系统所需要的节点模型,为系统的实现提供了操作的对象;系统的数据模型定义了系统内各种数据在对象(节点)里的分布,为系统的实现提供必须的数据支持。
In the last , the author discussed the design and realization process of waybill information synthetic application system in client . this system is designed in detail according to the user demanding , the data mode and specialist knowledge in repository , and some of soft engineering standards . it becomes an application including such as inquiring , statistic , data mining and analyzing function by using developing tools to programme , and it ' s the final production of study on the application of data mining and data warehouse technology 论文最后论述了货票信息前台综合应用系统的设计与实现过程,该系统根据用户需求、知识库中的数据模式与专家知识,以及相关的软件工程标准进行详细设计,利用开发工具编程实现,集查询、统计、数据挖掘与分析于一体,是数据挖掘与数据仓库技术应用研究的最终成果。
In part of the data warehouse technology , the background , the concept , the architecture , the data structure , the data mode , the pivotal technology and the establishing process of data warehouse are introduced . with regard to the data mining technology , the thesis sets forth the concept and characteristic , object mined , typical methods and tools used of data mining , and specifies the process of data mining . the concept and characteristic , the multiple dimensional data structure , the data processing mode and analytical technique of olap technology are depicted concerning the olap technology , and the architecture and data organization of the olap system are presented in detail 在数据仓库技术部分,介绍了数据仓库的产生背景、概念、体系结构、数据组织结构、数扼组织方式、数据仓库的关键技术以及数据仓库的创建步骤;在数据挖掘技术部分,介绍了数据挖掘的概念及特点、数据挖掘的目标、使用的典型方法及工具,重点阐述了数据挖掘的过程;在olap技术部分,介绍了olap的概念及特征、 olap的多维数据结构、数据处理方式和分析方法,重点阐述了olap系统的体系结构和数据组织的三种方式。
The view of combining of conception data mode and data warehouse has been pointed out . the main content of the paper includes the history of mis development , concept and developing methods , many questions in building mis and the traditional dealing ways . after that the paper expounds the theory of reference conception design , contract relationship theory and using of script building tools with parts 论文的主要内容如下:首先讲述了mis系统的发展历史,并介绍了mis的概念和开发的手段,其中包含了在开发mis过程中遇到的问题和传统的解决方法,然后分章节着重介绍了用于开发mis关系数据模型的参照式概念模型设计理论,用于面向对象程序设计的合约关系理论,以及脚本工具生成技术在mis快速成型技术中的应用。
