- The database must support at least one clearly defined language that includes functionality for data definition , data manipulation , data integrity , and database transaction control
数据库必须支持至少一个确切的定义语言包括数据定义，数据操纵，数据完整和数据库事务控制等功能。 - If the selected authentication method supports encapsulation for the purposes of integrity , authentication and / or confidentiality , the data are encapsulated using the method - dependent encapsulation
如果选定的鉴定方法支持数据完整、可靠和/或机密的封装，数据将被用方法选定的方式来封装。 - Simulation result showed when used for data processing , the method put forward could guarantee the integrity of data , compensate for the defects of recorded flight data effectively , increase the accuracy and reliability of the data
仿真结果表明，运用该方法进行数据处理，可以在保证数据完整准确的情况下，有效地弥补飞参记录数据的缺陷，提高了数据的准确性和可信度。 - As the application of distributed computing is used much more widely ， distributed database becomes a significant part of information management it avoids a lot of disadvantages of conventional centralized database ， and is applicable to many situations distributed database is a set of data which is the unity logic ， but in fact these data is located on different sites it is of high availability ， easy expansibility ， high concurrency ， high efficiency and etc in distributed system ， data redundancy is a method to improve the speed of query and the availability of system distributed query should shield the lower level details of data redundancy from end users ， distributed transaction should ensure data from disaccord this paper introduces basic conceptions of distributed database firstly ， discusses distributed transaction and concurrent control ， describes the development prototype mysql ’ s characters ， architecture and executive mechanism ， then shows the skeleton model of dpsql and exposes the strategy and algorithm of distributed query and distributed transaction ， at last analyzes the extra expenses and response delay of distributed processes this paper exposes the implementation mechanism of distributed query and distributed transaction emphatically distributed query uses the strategy of “ read one ， write a11 ” s0 in such a system if user ’ s requests are read - - only for the most part and the distribution of data redundancy is plausible ， efficiency is very high distributed transaction uses two - 。 phase commit protocol to ensure the consistency of global data ， which has less communication overhead
分布式查询需要向用户屏蔽数据冗余分散的底层细节，分布式事务处理要保证全局数据完整，这都是传统集中式数据库不曾面临的问题。本文首先介绍了分布式数据库的概念性问题；接着讨论了分布式事务涉及的定义及算法；然后描述了dpsql的原型mysql的特性、结构和执行机制；继而给出了dpsql的梗概模型，阐述了实现分布式查询和分布式事务处理的策略及算法；最后分析了进行分布式处理给系统增加的额外开销和客户端的额外响应延迟。本文重点描述了分布式查询和分布式事务处理的实现机制，分布式查询采用”读一个写全部”的本地优先策略，在读操作频繁的系统中，只要库的分布合理，单机效率极高，几乎无任何附加开销和延迟，而以整个系统的角度看来，吞吐量就更是优于单机系统；分布式事务处理采用两阶段提交协议，通信次数较少并能确实保证副本一致。
