摘要 网格技术的本质就是提高资源的共享能力和实现计算资源的协同处理能力。网格数据库就是使传统数据库能够充分利用网格平台的这种优势,实现传统数据库的存储、管理、处理、分析等能力的共享和协同。网格数据库中的事务也存在全局事务和局部事务之分,对全局事务要保证得到正确的执行结果,其串行化是关键。给出了网格数据库全局事务的形式化定义,以及全局事务实现串行化的条件,并进行了相关证明。 The essence of grid technology is to improve the ability of resource sharing and cooperative processing. In grid database, traditional database takes the advantage of grid to realize the sharing and cooperation of abilities of storage, management, processing and analysis. There are global transactions and local transactions in the grid database. The serializability of global transaction is very important in transaction management. The formal definition of global transactions and the condition of serializability are presented.
