摘要

分区依赖是分布式数据库系统中的一种数据分配约束。已经证明，这个约束可以用来加快查询处理。但是，某些更新操作可能会导致违反分布式数据库系统中现有的分区依赖关系。为了保持数据库的完整性和查询结果的准确性，必须检测和避免此类违规。我们提出了一些在分布式数据库系统中处理更新操作的策略，这样就不会违反分区依赖关系。

Update operation and partition dependency in distributed database systems

Partition dependency is a data allocation constraint in distributed database systems. It has been shown that this constraint can be used to speed up query processing. However, some update operations may cause violations of the existing partition dependencies in a distributed database system. In order to preserve database integrity and accuracy of query results, such violations must be detected and avoided. We present some strategies for processing update operations in distributed database systems such that there is no violation of partition dependency.
