【摘要】 分析了数据网格中数据不一致问题的产生以及数据网格中一致性服务的主要内容.基于数据访问特点,深入研究了数据网格中的一致性策略.结合上海医学网格第一阶段,即耳鼻喉医学网格的实际设计实现了一种新的数据一致性算法.最后还提出了在更为复杂的上海医学网格第二阶段,即乳腺癌医学网格中的一致性维护算法的思想.更多还原

【Abstract】 This paper discussed the data consistency and the content of consistency service in data grid. Based on the analysis of data accessing characteristic, it studied the consistency strategy in data grid and designed a new data consistency arithmetic which can be applied to Otolaryngology Medical Data Grid which is the first step of Shanghai Medical Data Grid. Finally, the paper proposed some solution of consistency in Galactophore Data Grid which is more complexes than Otolaryngology Medical Data Grid.更多还原
