A lot of projects use a relational database to store data , therefore any testing strategy needs to take into account what happens to the database during each test : if a test leaves a test database in an inconsistent state , all further tests are likely to fail 很多项目使用关系数据库存储数据，因而所有测试策略都需要考虑在每次测试过程中数据库中所发生的事情：如果测试使测试数据库处于不一致状态，那么后面的所有测试都可能失败！
In the chapter 5 , it puts forward the database application system of radar simulator and designs the module structure of the system . it further relates the functions of the database management module of radar simulator , and it discusses the database designing of the system 第五章提出了雷达模拟器数据库应用系统，设计出评估系统的模块体系结构，并进一步论述了雷达模拟器数据库管理模块的实现功能，以及评估系统中数据库的设计方法。
Discusses the role of the recovery model of a database in transaction log management , how to choose the recovery model for a database , transactions that are minimally logged in the bulk - logged and simple recovery models , and guidelines for switching recovery models 包含以下内容的相关介绍：事务日志管理中数据库恢复模式的角色、如何为数据库选择恢复模式、大容量日志恢复模式和简单恢复模式中按最小方式记录的事务以及切换恢复模式的原则。
Therefore , this thesis studies on the architecture , key technologies and methods for the implementation of the database access agent . furthermore , the emphasis of this thesis is focused on the database flux control , database encryption techniques , and encrypted network transmission 论文主要研究了数据库访问代理的系统结构、关键技术及实现方法，其中重点研究了数据库访问代理设计与实现中数据库服务器流量控制、数据库加密设计和网络传输加密等内容。
An dynamic algorithm of attribute reduction is presented . in fact , data are always changing in database , so a dynamic algorithm of attribute reduction based on rough logic is presented , which can get new minimum decision algorithm based on the original one when new object is added . it can avoid reduction from large original decision table , update and vindicate the original algorithm , and improve the efficiency of attribute reduction 2 .提出了一种增量式属性约简算法针对实际问题中数据库中的数据是不断变化的这一情况，以粗糙逻辑为基础，针对新加入的对象相对于原来的极小决策算法而言是全新的这种情况，提出了一种增量式属性约简算法，从而避免每次从庞大的原始决策表开始约简，实现了对原极小决策算法的更新与维护，提高了属性约简的效率。
The main task of this paper is to describe the model of relation database and meilan airport mis , and applies its basic idea into projects to solve the practical problem of meilan airport mis . at first , this paper introduces the theory , technology and method of rdbms , and also describes the implementation method and procedure of meilan airport . we also give you the e - r diagram and database flow drawings and the method of how to create database objects ( tables , views , triggers , procedure and so on ) 0 the paper also describes ordbms and replication in ibm db2 5 . 2 并根据美兰机场航班信息管理系统的实际需要，设计了符合关系模型的、规范化的数据库，并给出数据库系统结构设计e - r图和数据流程图，详细论述了在db2中数据库设计的方法和过程，数据库对象( tablespace 、 trigger 、 view 、 schema 、 procedure等)创建的技巧和应用，对ibmdb25 . 2中实现面向对象的数据库的概念、 db2中定时备份航班数据及如何在db2中实现分布式数据库的数据库复制( replication )进行了探讨和应用。
Secondly , it makes a study of the operating platform and terminal of video - conference system . thirdly , it goes into multimedia image format , c / s and b / s mode , the interface technology of database and how to transmit , saving and browsing images on network . at last , it also has a study of tcp / ip ( transmission control protocol / internet protocol ) protocol , h . 323 protocol , com + ( component object module ) , ado ( activex data objects ) , msmq ( microsoft message queue ) 本论文结合“ xmediabase视频会议系统”的实际项目，论述了视频会议系统的背景和应用前景，提出一套视频会议系统的设计方案，研究和开发了一个支持视频会议系统的运营平台和终端；深入研究了多媒体图像格式，图像在网络上的传输、存储与浏览， b / s模式以及在b / s模式中数据库的接口技术；同时对tcp ( transmissioncontrolprotocol ) / ip ( internetprotocol )协议、 h . 323协议、 com + ( componentobjectmodule )组件技术、 ado ( activexdataobjects )技术、消息队列服务等做了研究与开发工作。
The main works of this thesis are : briefly introduce the background of the project of this thesis , briefly introduce what are working procedures for surveying and mapping and its data stream , design the infrastructure and applications for the mis , design database applications for the mis , describe the network environment setting and its safety control , system test and other works 根据需求分析进行系统设计，包括管理信息系统结构及应用设计、系统中数据库的应用设计、系统运行的网络环境及安全措施、系统测试等。文章还介绍了系统实现的有关内容，在结论部分简要介绍了课题项目完成效果、系统的可推广性及可预期的社会效益和经济效益。
A systematic design is completed with the requirement of the clients into consideration , as well as a realization of the data base source ’ s backup , transforming and the date output and input to various office software . the technology discussed in this paper has been successfully applied to the information management system of some government department 基于以上的理论和技术,结合用户需求完成了管理信息系统中项目管理导入导出子系统的设计,实现了信息管理系统中数据库数据的逻辑备份、转换以及数据库与多种办公软件间的数据导入导出功能。
