数据一致性

• In the thesis , it illustrates some studies about replacement strategy and then proposes a kind of replacement strategy , which is based on cache data priority and timestamp . in the thesis , it simply introduces some techniques to resolve coherence question
  在缓存数据管理策略中给出了一种采用时间戳解决物流行业子系统在“移动计算”环境中的数据一致性问题的方法。
• In the 4th chapter , based on technologies in quo , we proposed a data consistency - protecting framework that includes lock mechanism , data protecting model , multi - version management and process - level transaction failure model
  论文第四章在现有技术基础上，结合加锁机制、数据保护模型、数据多版本管理以及流程级事务故障处理模型，给出了一套较好的相关数据一致性保护框架。
• In this system , however , the shared units would have several copies in different nodes in order to reduce the times of remote accesses , and the system would maintain the data consistency between different copies through data consistency model
  然而，在分布式共享系统中，为了减少非本地数据的存取，通常系统会在不同节点保留数据的拷贝并用模型来约束不同拷贝间的数据一致性。
• Then , the integrating of gis & ems and common information model ( cim ) based design of the parameter database , which are the two main technologies of the development of the parameter management system , are discussed in the thesis
  其中，基于公共信息模型cim ( commoninformationmodel )的电网参数数据库设计使gis与ems的数据一致性问题得到了较好的解决，并为系统今后的扩展打下了基础。
• Data coherence is an important issue in dual - core application . by analysis the system space and task space , the basic principle for application on dual - core is the independence of the task space and the reentrant of the kernel operation
  通过对内核的运行空间,任务的运行空间进行分析,推导出在双核处理器环境中保证数据一致性的基本条件:任务运行空间的相对独立性和内核操作的可重入性。
• In the last main part of this article , we discuss the critical technical problems , such as the system security and the authority control , the document transmission , the consistency of data , and present corresponding solutions
  在此基础上，本文研究了基于lotusdomino notes平台集成文档数据库与关系数据库的关键技术：系统安全性及权限控制、公文流转、数据一致性等，并提出相应的解决方案。
• The simulation results show that the 2dcma algorithm has better performance than that of mork s when maintaining data consistency . and the 2dcma algorithm has better performance than that of centralized view maintenance algorithm when maintaining definition consistency
  我们的数据一致性维护算法是依据该规则系统提出来的，该算法主要考虑局部视图和全局视图的维护，当然，它也适合peer视图维护。
• Hence problems on the traditional serial management are solved such as too long designing cycle , frequent modification , bad data consistency , security and share ability , difficult in query etc . the dissertation has a research on concurrent design model of order - oriented enterprises
  解决了传统串行管理模式下，产品设计周期长，更改频繁，数据一致性、安全性和共享性差，数据查询困难等问题。
• In the project i participated in the design of the whole application model and designed the communication program of the maintenance of the distributed data and the relative data structure and implemented the client side of the communication program
  本人在整个项目中参与了整个系统应用模型的总体设计，设计了分布式数据一致性维护的通讯子程序和相关数据库结构的设计，实现了通讯子程序的客户端程序。
• Multidatabase can shield the user and application from the difference of local database , and provide global transaction management , and maintain consistency of data within the local database . multidatabase technology has been accepted in the world
  多库系统为用户和应用程序屏蔽了底层数据库操作环境的差异，提供全局事务处理能力，并维护各结点上ldb的数据一致性，从较深的层次解决了异构数据库互操作问题。
