数据分布在信息系统中的设计与实现

Design and implement data distributing in information system

如何结合系统特点 ,选择合适的数据分布策略将影响系统的整体运行性能 .本文重点讨论了应用层的数据分布 ,分析了数据冗余模型的概念、实现以及对系统的影响 ;同时简要论述了数据访问层的数据分割模型的概念与实现 .

To decide the strategies of data distributing combing with system traits is one of the most important aspects that could affect the system's run-time efficiency. The article mainly focuses on two data distributing models in application layer and data access layer: Data Redundant Model and Data Partition Model, and analyses the concepts and the implementation of the models.
