The Question about Dimensional Summarizability and its Countermeasures

摘要：

In OLAP application, aggregation is the usual technique to improve the response speed of the users query. However, there have been few attempts to completely characterize the ability to summarize measures along some dimensions. Based on this situation, this paper gives some basic definitions about the dimension summarizability at first, and represents its taxonomy. Then describes the technique of judging the summarizability in detail, and finally, its countermeasures are introduced.
