A data base management system was build by taking advantage of pc . we have designed correspondence software based on virtual instrument and front end interface using visual basic 6 . 0 软件方面,在windows98操作系统的平台上,以visualbasic6 . 0高级语言为工具,设计了相应的虚拟仪器软件系统,实现了程序代码和前端界面。
This thesis utilized object - oriented developing environment and sql server data base management system as the developing instrument to finish the design and maintaining of knowledge base , the expression of knowledge and the realization of reasoning machine 并用sqlserver数据库管理系统和vc + +面向对象集成开发环境作为开发工具,完成了知识库的设计与维护,知识的解释以及推理机的实现。
This thesis utilized object - oriented developing environment delphi6 and sql server data base management system as the developing instrument , and adopt component object model ( com ) to design a prototype of expert system based on object - oriented 本论文用sqlserver数据库管理系统和delphi6面向对象集成开发环境作为开发工具,采用组件对象模型( com )方法设计了一个基于面向对象的专家系统原型。
With the development of information technology , data base management system ( dbms ) is widely used in quality management ( qm ) , mass data has been accumulated in database of enterprise during the process of quality management 随着企业信息化的发展,数据库技术广泛应用于质量管理中,航空企业积累了大量的数据,如何发现这些数据背后隐藏的有用信息以及运用这些信息指导生产,成为企业亟待解决的问题。
In this part , the first work is pretreatment of a numerical model , including creating calculating grids automatically , improvement of the linear boundary technique and so on . the second work is to estimate the siltation of a basin or channel by liu ' s equation . the third work is to build an edbms ( engineering data base management system ) for the result of mathematical model 其中主要的工作是:其中主要的工作一是数学模型的前处理,计算网格自动生成,线边界法的优化;二是应用刘家驹公式在长江口深水航道治理工程地理信息系统的支持下实现港池、航槽开挖的实时回淤估算;三是将计算成果形成gis管理和支持下的工程数据库系统( engineeringdatabasemanagementsystem ) ,同时尝试解决时间序列数据如地形冲淤变化,潮位、流速过程的分析、查询和显示问题,并实现实时、互动的动态演示及三维可视化。
At present , people are faced with proliferate data which provide favorable conditions for establishes of data warehouse . at present , data base management system can succeed in realizing record modification and query . with the rapid increase of data , , query and stat ca n ' t meet practical need and find relation of data so that : knowledge is lacked 与日趋成熟的数据管理技术与软件工具相比,人们所依赖的数据分析工具功能,却无法有效地为决策者提供其决策支持所需要的相关知识,从而形成了一种“丰富的数据,贫乏的知识”之独特的现象,人们迫切需要有新的有效手段对这些数据进行分析,数据挖掘方法就是为满足这种需求而产生并迅速发展起来的。
The basic data base of village and town during 1985 - 2000 is established by data base management system . through the exclusive spacial analysis function , spacial data base and attribute data base are mated into a spacial - attribute - unified data base . then the spacial evolution maps and dynamic type map of pred system are formed , and spacial difference and evolution law are further studied 应用gis建立全县乡镇级行政区划空间数据库,并借助数据库管理系统( dbms )建立1985 2000年全县分乡镇pred系统基础数据库,应用gis特有的空间分析功能,将相关的空间数据与属性数据进行匹配处理,建立“空间?属性一体化数据库” ,在此基础上,生成pred系统空间演变图、动态类型图,并进一步分析其空间分异及演变规律。
System have two database , one is main memory database in front ; other is oracle data base management system in back . this not only satisfies the request of in - line monitoring , but also actualizes the management to data . focusing the diagnose function , paper actualizes design of main memory database and faults diagnose expert system and background database with java language which is independent of operating system and is oriented to object 系统具有以下特点: 1 、充分利用巡回监测装置采集的数据和瞬时转速诊断技术的特点,采用简洁实用的硬件结构,构建在线故障诊断系统; 2 、采用两种触发方式进行故障推理,实现自动分析诊断和交互诊断相结合的诊断模式; 3 、设计内存数据库作前端、 oracle数据库平台作后端的双数据库模式,系统既满足实时监测的要求,又实现了数据管理的功能。
